feat(sessions): add --sanitize flag to sessions export

Port from anomalyco/opencode#22489: redact user/model content
from session exports before sharing for bug reports or training data.

Adds hermes_state.sanitize_session_export() which returns a deep-copied
session with:

- Message content, reasoning, and reasoning_details replaced with
  [redacted:<kind>:<id>] tokens
- Tool-call arguments redacted (tool id, type, and function name preserved)
- Session title and system_prompt redacted
- All structural/metric fields preserved: ids, timestamps, token counts,
  tool names, finish reasons, model info, cost data, message counts

Wired into 'hermes sessions export --sanitize' (applies to both
--session-id and full exports). The flag is opt-in — default behaviour
is unchanged. User sees '(sanitized)' suffix on the export summary
when the flag is active.

5 new tests covering content redaction, reasoning/tool-call redaction,
empty-value preservation, input immutability, and reasoning_details
block structure.

E2E verified: raw export still leaks sk-proj-* API keys and usernames,
sanitized export replaces them with redaction tokens while preserving
model names, tool names, and tool call ids.

-## TUI Architecture (ui-tui + tui_gateway)
-
-The TUI is a full replacement for the classic (prompt_toolkit) CLI, activated via `hermes --tui` or `HERMES_TUI=1`.
-
-### Process Model
-
-```
-hermes --tui
-  └─ Node (Ink)  ──stdio JSON-RPC──  Python (tui_gateway)
-       │                                  └─ AIAgent + tools + sessions
-       └─ renders transcript, composer, prompts, activity
-```
-
-TypeScript owns the screen. Python owns sessions, tools, model calls, and slash command logic.
-
-### Transport
-
-Newline-delimited JSON-RPC over stdio. Requests from Ink, events from Python. See `tui_gateway/server.py` for the full method/event catalog.
-
-### Key Surfaces
-
-| Surface | Ink component | Gateway method |
-|---------|---------------|----------------|
-| Chat streaming | `app.tsx` + `messageLine.tsx` | `prompt.submit` → `message.delta/complete` |
-| Tool activity | `thinking.tsx` | `tool.start/progress/complete` |
-| Approvals | `prompts.tsx` | `approval.respond` ← `approval.request` |
-| Clarify/sudo/secret | `prompts.tsx`, `maskedPrompt.tsx` | `clarify/sudo/secret.respond` |
-| Session picker | `sessionPicker.tsx` | `session.list/resume` |
-| Slash commands | Local handler + fallthrough | `slash.exec` → `_SlashWorker`, `command.dispatch` |
-| Completions | `useCompletion` hook | `complete.slash`, `complete.path` |
-| Theming | `theme.ts` + `branding.tsx` | `gateway.ready` with skin data |
-
-### Slash Command Flow
-
-1. Built-in client commands (`/help`, `/quit`, `/clear`, `/resume`, `/copy`, `/paste`, etc.) handled locally in `app.tsx`
-2. Everything else → `slash.exec` (runs in persistent `_SlashWorker` subprocess) → `command.dispatch` fallback
-
-### Dev Commands
-
-```bash
-cd ui-tui
-npm install       # first time
-npm run dev       # watch mode (rebuilds hermes-ink + tsx --watch)
-npm start         # production
-npm run build     # full build (hermes-ink + tsc)
-npm run type-check # typecheck only (tsc --noEmit)
-npm run lint      # eslint
-npm run fmt       # prettier
-npm test          # vitest

 ## Testing
 
-**ALWAYS use `scripts/run_tests.sh`** — do not call `pytest` directly. The script enforces
-hermetic environment parity with CI (unset credential vars, TZ=UTC, LANG=C.UTF-8,
-4 xdist workers matching GHA ubuntu-latest). Direct `pytest` on a 16+ core
-developer machine with API keys set diverges from CI in ways that have caused
-multiple "works locally, fails in CI" incidents (and the reverse).

-```
-
-### Why the wrapper (and why the old "just call pytest" doesn't work)
-
-Five real sources of local-vs-CI drift the script closes:
-
-| | Without wrapper | With wrapper |
-|---|---|---|
-| Provider API keys | Whatever is in your env (auto-detects pool) | All `*_API_KEY`/`*_TOKEN`/etc. unset |
-| HOME / `~/.hermes/` | Your real config+auth.json | Temp dir per test |
-| Timezone | Local TZ (PDT etc.) | UTC |
-| Locale | Whatever is set | C.UTF-8 |
-| xdist workers | `-n auto` = all cores (20+ on a workstation) | `-n 4` matching CI |
-
-`tests/conftest.py` also enforces points 1-4 as an autouse fixture so ANY pytest
-invocation (including IDE integrations) gets hermetic behavior — but the wrapper
-is belt-and-suspenders.
-
-### Running without the wrapper (only if you must)
-
-If you can't use the wrapper (e.g. on Windows or inside an IDE that shells
-pytest directly), at minimum activate the venv and pass `-n 4`:
-
 ```bash
 source venv/bin/activate
-python -m pytest tests/ -q -n 4
+python -m pytest tests/ -q          # Full suite (~3000 tests, ~3 min)
+python -m pytest tests/test_model_tools.py -q   # Toolset resolution
+python -m pytest tests/test_cli_init.py -q       # CLI config loading
+python -m pytest tests/gateway/ -q               # Gateway tests
+python -m pytest tests/tools/ -q                 # Tool-level tests
 ```
 
-Worker count above 4 will surface test-ordering flakes that CI never sees.
-

-# Ink Gateway TUI Migration — Post-mortem
-
-Planned: 2026-04-01 · Delivered: 2026-04 · Status: shipped, classic (prompt_toolkit) CLI still present
-
-## What Shipped
-
-Three layers, same repo, Python runtime unchanged.
-
-```
-ui-tui (Node/TS)  ──stdio JSON-RPC──▶  tui_gateway (Py)  ──▶  AIAgent (run_agent.py)
-```
-
-### Backend — `tui_gateway/`
-
-```
-tui_gateway/
-├── entry.py          # subprocess entrypoint, stdio read/write loop
-├── server.py         # everything: sessions dict, @method handlers, _emit
-├── render.py         # stream renderer, diff rendering, message rendering
-├── slash_worker.py   # subprocess that runs hermes_cli slash commands
-└── __init__.py
-```
-
-`server.py` owns the full runtime-control surface: session store (`_sessions: dict[str, dict]`), method registry (`@method("…")` decorator), event emitter (`_emit`), agent lifecycle (`_make_agent`, `_init_session`, `_wire_callbacks`), approval/sudo/clarify round-trips, and JSON-RPC dispatch.
-
-Protocol methods (`@method(...)` in `server.py`):
-
-- session: `session.{create, resume, list, close, interrupt, usage, history, compress, branch, title, save, undo}`
-- prompt: `prompt.{submit, background, btw}`
-- tools: `tools.{list, show, configure}`
-- slash: `slash.exec`, `command.{dispatch, resolve}`, `commands.catalog`, `complete.{path, slash}`
-- approvals: `approval.respond`, `sudo.respond`, `clarify.respond`, `secret.respond`
-- config/state: `config.{get, set, show}`, `model.options`, `reload.mcp`
-- ops: `shell.exec`, `cli.exec`, `terminal.resize`, `input.detect_drop`, `clipboard.paste`, `paste.collapse`, `image.attach`, `process.stop`
-- misc: `agents.list`, `skills.manage`, `plugins.list`, `cron.manage`, `insights.get`, `rollback.{list, diff, restore}`, `browser.manage`
-
-Protocol events (`_emit(…)` → handled in `ui-tui/src/app/createGatewayEventHandler.ts`):
-
-- lifecycle: `gateway.{ready, stderr}`, `session.info`, `skin.changed`
-- stream: `message.{start, delta, complete}`, `thinking.delta`, `reasoning.{delta, available}`, `status.update`
-- tools: `tool.{start, progress, complete, generating}`, `subagent.{start, thinking, tool, progress, complete}`
-- interactive: `approval.request`, `sudo.request`, `clarify.request`, `secret.request`
-- async: `background.complete`, `btw.complete`, `error`

-### CLI entry points — `hermes_cli/main.py`
-
-- `hermes --tui`      → `node dist/entry.js` (auto-builds when `.ts`/`.tsx` newer than `dist/entry.js`)
-- `hermes --tui --dev` → `tsx src/entry.tsx` (skip build)
-- `HERMES_TUI_DIR=…`  → external prebuilt dist (nix, distro packaging)
-
-## Diverged From Original Plan
-
-| Plan | Reality | Why |
-|---|---|---|
-| `tui_gateway/{controller,session_state,events,protocol}.py` | all collapsed into `server.py` | no second consumer ever emerged, keeping one file cheaper than four |
-| `ui-tui/src/main.tsx` | split into `entry.tsx` (bootstrap) + `app.tsx` (shell) | boot banner + early python spawn wanted a pre-React moment |
-| `ui-tui/src/state/store.ts` | three nanostores (`uiStore`, `turnStore`, `overlayStore`) | separate lifetimes: ui persists, turn resets per reply, overlay is modal |
-| `approval.requested` / `sudo.requested` / `clarify.requested` | `*.request` (no `-ed`) | cosmetic |
-| `session.cancel` | dropped | `session.interrupt` covers it |
-| `HERMES_EXPERIMENTAL_TUI=1`, `display.experimental_tui: true`, `/tui on/off/status` | none shipped | `--tui` went from opt-in to first-class without an experimental phase |
-
-## Post-migration Additions (not in original plan)
-
-- **Async `session.create`** — returns sid in ~1ms, agent builds on a background thread, `session.info` broadcasts when ready; `_wait_agent()` gates every agent-touching handler via `_sess`
-- **`bootBanner`** — raw-ANSI logo painted to stdout at T≈2ms, before Ink loads; `<AlternateScreen>` wipes it seamlessly when React mounts
-- **Selection uniform bg** — `theme.color.selectionBg` wired via `useSelection().setSelectionBgColor`; replaces SGR-inverse per-cell swap that fragmented over amber/gold fg
-- **Slash command registry** — TS-owned commands in `app/slash/commands/{core,ops,session}.ts`, everything else falls through to `slash.exec` (python worker)
-- **Turn store + controller split** — imperative singleton (`turnController`) holds refs/timers, nanostore (`turnStore`) holds render-visible state
-
-## What's Still Open
-
-- **Classic CLI not deleted.** `cli.py` still has ~80 `prompt_toolkit` references; classic REPL is still the default when `--tui` is absent. The original plan's "Cut 4 · prompt_toolkit removal later" hasn't happened.
-- **No config-file opt-in.** `HERMES_EXPERIMENTAL_TUI` and `display.experimental_tui` were never built; only the CLI flag exists. Fine for now — if we want "default to TUI", a single line in `main.py` flips it.

-# When a new gateway starts with ``--replace``, it SIGTERMs the existing

-# the gateway with code 1 so ``Restart=on-failure`` can revive it after
-# unexpected kills — but that also means a --replace takeover target
-# exits 1, which tricks systemd into reviving it 30 seconds later,
-# starting a flap loop against the replacer when both services are
-# enabled in the user's systemd (e.g. ``hermes.service`` + ``hermes-
-# gateway.service``).
-#
-# The takeover marker breaks the loop: the replacer writes a short-lived
-# file naming the target PID + start_time BEFORE sending SIGTERM.
-# The target's shutdown handler reads the marker and, if it names
-# this process, treats the SIGTERM as a planned takeover and exits 0.
-# The marker is unlinked after the target has consumed it, so a stale
-# marker left by a crashed replacer can grief at most one future
-# shutdown on the same PID — and only within _TAKEOVER_MARKER_TTL_S.

-    Nous credentials are read at runtime from two independent locations:

-      ``resolve_nous_runtime_credentials()`` during 401 recovery and by
-      ``_seed_from_singletons()`` during pool load.
-    - ``credential_pool.nous``: used by the runtime ``pool.select()`` path.
-
-    Historically ``hermes auth add nous`` wrote a ``manual:device_code`` pool
-    entry only, skipping ``providers.nous``.  When the 24h agent_key TTL
-    expired, the recovery path read the empty singleton state and raised
-    ``AuthError`` silently (``logger.debug`` at INFO level).
-
-    This helper writes ``providers.nous`` then calls ``load_pool("nous")`` so
-    ``_seed_from_singletons`` materialises the canonical ``device_code`` pool
-    entry from the singleton.  Re-running login upserts the same entry in
-    place; the pool never accumulates duplicate device_code rows.
-
-    ``label`` is an optional user-chosen display name (from
-    ``hermes auth add nous --label <name>``).  It gets embedded in the
-    singleton state so that ``_seed_from_singletons`` uses it as the pool
-    entry's label on every subsequent ``load_pool("nous")`` instead of the
-    auto-derived token fingerprint.  When ``None``, the auto-derived label
-    via ``label_from_token`` is used (unchanged default behaviour).

-# ComfyUI
-
-Control a running ComfyUI instance from Hermes via its REST API. Queue workflow prompts, generate images and video, upload inputs, check progress, and retrieve outputs — all through `execute_code`.
-
-## When to Use
-
-- User asks to generate images with Stable Diffusion, SDXL, Flux, or other diffusion models
-- User wants to run a specific ComfyUI workflow
-- User wants to chain generative steps (txt2img → upscale → face restore)
-- User needs ControlNet, inpainting, img2img, or other advanced pipelines
-- User asks to manage ComfyUI queue or check generation progress
-
-## Setup
-
-ComfyUI must be running and reachable. Three options:
-
-### Option A: Local
-
-**Requires Python 3.10+.**
-
-    git clone https://github.com/comfyanonymous/ComfyUI.git
-    cd ComfyUI
-    python3 -m venv venv && source venv/bin/activate
-    pip install torch torchvision torchaudio
-    pip install -r requirements.txt
-    python main.py --listen 127.0.0.1 --port 8188
-
-GPU acceleration is auto-detected (CUDA on NVIDIA, MPS on Apple Silicon).
-
-### Option B: Comfy Cloud
-
-1. Sign up at https://platform.comfy.org
-2. Generate an API key at https://platform.comfy.org/profile/api-keys (**requires paid plan**)
-3. Set in `~/.hermes/.env`:
-
-```
-COMFYUI_URL=https://cloud.comfy.org/api
-COMFYUI_API_KEY=<your-key>
-```
-
-### Option C: Remote instance
-
-Point `COMFYUI_URL` at any reachable ComfyUI server:
-
-```
-COMFYUI_URL=http://192.168.1.100:8188
-```
-
-### Verify connection
-
-```python
-from hermes_tools import terminal
-r = terminal("curl -s ${COMFYUI_URL:-http://127.0.0.1:8188}/system_stats | python3 -m json.tool | head -5")
-print(r["output"])
-```
-
-## Core Pattern — ComfyUI Helper
-
-Use this helper inside `execute_code` for all ComfyUI interactions:
-
-```python
-import json, time, urllib.request, urllib.parse, urllib.error, uuid, os
-
-COMFY_URL = os.getenv("COMFYUI_URL", "http://127.0.0.1:8188")

-## Common Workflows
-
-### Text-to-Image (Minimal)
-
-Always call `list_models("checkpoints")` first to get the exact filename.
-
-```python
-# Discover which checkpoint is installed
-models = list_models("checkpoints")
-ckpt = models[0]  # use first available
-
-workflow = {
-    "3": {
-        "class_type": "KSampler",
-        "inputs": {
-            "seed": 42,
-            "steps": 20,
-            "cfg": 7.0,
-            "sampler_name": "euler",
-            "scheduler": "normal",
-            "denoise": 1.0,
-            "model": ["4", 0],
-            "positive": ["6", 0],
-            "negative": ["7", 0],
-            "latent_image": ["5", 0],
-        },
-    },
-    "4": {
-        "class_type": "CheckpointLoaderSimple",
-        "inputs": {"ckpt_name": ckpt},
-    },
-    "5": {
-        "class_type": "EmptyLatentImage",
-        "inputs": {"width": 512, "height": 512, "batch_size": 1},
-    },
-    "6": {
-        "class_type": "CLIPTextEncode",
-        "inputs": {
-            "text": "a beautiful sunset over mountains, photorealistic",
-            "clip": ["4", 1],
-        },
-    },
-    "7": {
-        "class_type": "CLIPTextEncode",
-        "inputs": {
-            "text": "ugly, blurry, low quality",
-            "clip": ["4", 1],
-        },
-    },

-        "class_type": "VAEDecode",
-        "inputs": {"samples": ["3", 0], "vae": ["4", 2]},
-    },
-    "9": {
-        "class_type": "SaveImage",
-        "inputs": {"filename_prefix": "hermes", "images": ["8", 0]},
-    },
-}
-
-pid = queue_prompt(workflow)
-result = wait_for_completion(pid)
-
-# Extract output image filename
-for node_id, node_output in result["outputs"].items():
-    if "images" in node_output:
-        for img in node_output["images"]:
-            img_data = get_image(img["filename"], img["subfolder"], img["type"])
-            with open(f"/tmp/{img['filename']}", "wb") as f:
-                f.write(img_data)
-            print(f"Saved: /tmp/{img['filename']}")
-```
-
-### Parameterized Generation
-
-When the user asks to generate an image, build the workflow by modifying the template:
-- **Prompt**: Set node "6" inputs.text to the user's positive prompt
-- **Negative**: Set node "7" inputs.text (default: "ugly, blurry, low quality")
-- **Model**: Set node "4" inputs.ckpt_name (use `list_models()` to find available ones)
-- **Size**: Set node "5" inputs.width/height (SD 1.5: 512, SDXL: 1024, Flux: 1024)
-- **Steps/CFG**: Set node "3" inputs.steps and inputs.cfg
-- **Seed**: Set node "3" inputs.seed (random for variation, fixed for reproducibility)
-
-### Loading User Workflows
-
-Users often have saved workflow JSON files. Two formats exist:
-
-1. **API format** — flat node dict, directly usable with `queue_prompt()`:
-   ```python
-   with open("workflow_api.json") as f:
-       workflow = json.load(f)
-   pid = queue_prompt(workflow)
-   ```
-
-2. **UI format** — includes visual layout, NOT directly usable. Look for the
-   `"prompt"` key inside the exported data, or ask the user to export as API format
-   from ComfyUI's menu: Save (API Format).
-
-### Checking Available Nodes
-
-```python
-# List all available node types
-info = comfy_api("GET", "/object_info")
-print(f"Total node types: {len(info)}")
-
-# Get info for a specific node
-ksampler_info = comfy_api("GET", "/object_info/KSampler")
-print(json.dumps(ksampler_info, indent=2)[:500])
-```
-
-## Queue Management
-
-```python
-# Check what's running/pending
-status = get_queue_status()
-running = status.get("queue_running", [])
-pending = status.get("queue_pending", [])
-print(f"Running: {len(running)}, Pending: {len(pending)}")
-
-# Cancel everything
-if pending:
-    comfy_api("POST", "/queue", {"clear": True})
-
-# Interrupt current generation
-interrupt()
-```
-
-## Advanced: Native MCP Server Integration
-
-For deeper integration with dedicated MCP tools, configure an external ComfyUI
-MCP server in `~/.hermes/config.yaml`:
-
-```yaml
-mcp_servers:
-  comfyui:
-    command: "npx"
-    args: ["-y", "comfyui-mcp-server"]
-    env:
-      COMFYUI_URL: "http://127.0.0.1:8188"
-```
-
-This registers ComfyUI operations as native Hermes tools (prefixed `mcp_comfyui_*`).
-See the `native-mcp` skill for MCP server configuration details.
-
-## Pitfalls
-
-1. **Python 3.10+ required**: ComfyUI's dependencies require Python 3.10+.
-
-2. **API format vs UI format**: ComfyUI Save produces UI format (with layout info).
-   Only API format works with POST /prompt. Use "Save (API Format)" or extract
-   the `"prompt"` key from the UI format JSON.
-
-3. **Node IDs are strings**: Always use `"3"` not `3` in workflow dicts. Links
-   between nodes use `["source_node_id", output_index]` arrays.
-
-4. **Model names must be exact**: Use `list_models("checkpoints")` to get the
-   exact filename including extension. Names are case-sensitive.
-
-5. **Long generations**: Complex workflows (high steps, large images, video) can
-   take minutes. Set `wait_for_completion(timeout=600)` for heavy workloads.
-
-6. **VRAM/memory exhaustion**: Large models + high resolution can OOM. Use
-   `comfy_api("POST", "/free", {"unload_models": True})` to free memory between
-   generations, or start ComfyUI with `--lowvram` / `--cpu` flags.
-
-7. **Custom nodes**: Many workflows require custom nodes (ControlNet, IPAdapter,
-   AnimateDiff, etc.). If a workflow fails with "class_type not found", the user
-   needs to install the missing node pack via ComfyUI Manager or manually.
-
-8. **Output path**: Generated images are saved in ComfyUI's `output/` directory.
-   Use `get_image()` to download them to a local path the user can access.
-
-9. **Concurrent generations**: ComfyUI queues prompts sequentially by default.
-   Multiple `queue_prompt()` calls will queue, not parallelize.
-
-10. **Sampler/scheduler compatibility**: Not all combinations work with all models.
-    Safe defaults — SD 1.5/SDXL: `euler` + `normal`, CFG 7.0.
-    Flux: `euler` + `simple`, CFG 1.0. SD3: `euler` + `sgm_uniform`, CFG 4.5.

-description: Generate flat, minimal light/dark-aware SVG diagrams as standalone HTML files, using a unified educational visual language with 9 semantic color ramps, sentence-case typography, and automatic dark mode. Best suited for educational and non-software visuals — physics setups, chemistry mechanisms, math curves, physical objects (aircraft, turbines, smartphones, mechanical watches), anatomy, floor plans, cross-sections, narrative journeys (lifecycle of X, process of Y), hub-spoke system integrations (smart city, IoT), and exploded layer views. If a more specialized skill exists for the subject (dedicated software/cloud architecture, hand-drawn sketches, animated explainers, etc.), prefer that — otherwise this skill can also serve as a general-purpose SVG diagram fallback with a clean educational look. Ships with 15 example diagrams.

-# Concept Diagrams
-
-Generate production-quality SVG diagrams with a unified flat, minimal design system. Output is a single self-contained HTML file that renders identically in any modern browser, with automatic light/dark mode.
-
-## Scope
-
-**Best suited for:**
-- Physics setups, chemistry mechanisms, math curves, biology
-- Physical objects (aircraft, turbines, smartphones, mechanical watches, cells)
-- Anatomy, cross-sections, exploded layer views
-- Floor plans, architectural conversions
-- Narrative journeys (lifecycle of X, process of Y)
-- Hub-spoke system integrations (smart city, IoT networks, electricity grids)
-- Educational / textbook-style visuals in any domain
-- Quantitative charts (grouped bars, energy profiles)
-
-**Look elsewhere first for:**
-- Dedicated software / cloud infrastructure architecture with a dark tech aesthetic (consider `architecture-diagram` if available)
-- Hand-drawn whiteboard sketches (consider `excalidraw` if available)
-- Animated explainers or video output (consider an animation skill)
-
-If a more specialized skill is available for the subject, prefer that. If none fits, this skill can serve as a general-purpose SVG diagram fallback — the output will carry the clean educational aesthetic described below, which is a reasonable default for almost any subject.
-
-## Workflow
-
-1. Decide on the diagram type (see Diagram Types below).
-2. Lay out components using the Design System rules.
-3. Write the full HTML page using `templates/template.html` as the wrapper — paste your SVG where the template says `<!-- PASTE SVG HERE -->`.
-4. Save as a standalone `.html` file (for example `~/my-diagram.html` or `./my-diagram.html`).
-5. User opens it directly in a browser — no server, no dependencies.
-
-Optional: if the user wants a browsable gallery of multiple diagrams, see "Local Preview Server" at the bottom.
-
-Load the HTML template:
-```
-skill_view(name="concept-diagrams", file_path="templates/template.html")
-```
-
-The template embeds the full CSS design system (`c-*` color classes, text classes, light/dark variables, arrow marker styles). The SVG you generate relies on these classes being present on the hosting page.
-
----
-
-## Design System
-
-### Philosophy
-
-- **Flat**: no gradients, drop shadows, blur, glow, or neon effects.
-- **Minimal**: show the essential. No decorative icons inside boxes.
-- **Consistent**: same colors, spacing, typography, and stroke widths across every diagram.
-- **Dark-mode ready**: all colors auto-adapt via CSS classes — no per-mode SVG.
-
-### Color Palette
-
-9 color ramps, each with 7 stops. Put the class name on a `<g>` or shape element; the template CSS handles both modes.
-
-| Class      | 50 (lightest) | 100     | 200     | 400     | 600     | 800     | 900 (darkest) |
-|------------|---------------|---------|---------|---------|---------|---------|---------------|
-| `c-purple` | #EEEDFE | #CECBF6 | #AFA9EC | #7F77DD | #534AB7 | #3C3489 | #26215C |
-| `c-teal`   | #E1F5EE | #9FE1CB | #5DCAA5 | #1D9E75 | #0F6E56 | #085041 | #04342C |
-| `c-coral`  | #FAECE7 | #F5C4B3 | #F0997B | #D85A30 | #993C1D | #712B13 | #4A1B0C |
-| `c-pink`   | #FBEAF0 | #F4C0D1 | #ED93B1 | #D4537E | #993556 | #72243E | #4B1528 |
-| `c-gray`   | #F1EFE8 | #D3D1C7 | #B4B2A9 | #888780 | #5F5E5A | #444441 | #2C2C2A |
-| `c-blue`   | #E6F1FB | #B5D4F4 | #85B7EB | #378ADD | #185FA5 | #0C447C | #042C53 |
-| `c-green`  | #EAF3DE | #C0DD97 | #97C459 | #639922 | #3B6D11 | #27500A | #173404 |
-| `c-amber`  | #FAEEDA | #FAC775 | #EF9F27 | #BA7517 | #854F0B | #633806 | #412402 |
-| `c-red`    | #FCEBEB | #F7C1C1 | #F09595 | #E24B4A | #A32D2D | #791F1F | #501313 |
-
-#### Color Assignment Rules
-
-Color encodes **meaning**, not sequence. Never cycle through colors like a rainbow.
-
-- Group nodes by **category** — all nodes of the same type share one color.
-- Use `c-gray` for neutral/structural nodes (start, end, generic steps, users).
-- Use **2-3 colors per diagram**, not 6+.
-- Prefer `c-purple`, `c-teal`, `c-coral`, `c-pink` for general categories.
-- Reserve `c-blue`, `c-green`, `c-amber`, `c-red` for semantic meaning (info, success, warning, error).
-
-Light/dark stop mapping (handled by the template CSS — just use the class):
-- Light mode: 50 fill + 600 stroke + 800 title / 600 subtitle
-- Dark mode:  800 fill + 200 stroke + 100 title / 200 subtitle
-
-### Typography
-
-Only two font sizes. No exceptions.
-
-| Class | Size | Weight | Use |
-|-------|------|--------|-----|
-| `th`  | 14px | 500    | Node titles, region labels |
-| `ts`  | 12px | 400    | Subtitles, descriptions, arrow labels |
-| `t`   | 14px | 400    | General text |
-
-- **Sentence case always.** Never Title Case, never ALL CAPS.
-- Every `<text>` MUST carry a class (`t`, `ts`, or `th`). No unclassed text.
-- `dominant-baseline="central"` on all text inside boxes.
-- `text-anchor="middle"` for centered text in boxes.
-
-**Width estimation (approx):**
-- 14px weight 500: ~8px per character
-- 12px weight 400: ~6.5px per character
-- Always verify: `box_width >= (char_count × px_per_char) + 48` (24px padding each side)
-
-### Spacing & Layout
-
-- **ViewBox**: `viewBox="0 0 680 H"` where H = content height + 40px buffer.
-- **Safe area**: x=40 to x=640, y=40 to y=(H-40).
-- **Between boxes**: 60px minimum gap.
-- **Inside boxes**: 24px horizontal padding, 12px vertical padding.
-- **Arrowhead gap**: 10px between arrowhead and box edge.
-- **Single-line box**: 44px height.
-- **Two-line box**: 56px height, 18px between title and subtitle baselines.
-- **Container padding**: 20px minimum inside every container.
-- **Max nesting**: 2-3 levels deep. Deeper gets unreadable at 680px width.
-
-### Stroke & Shape
-
-- **Stroke width**: 0.5px on all node borders. Not 1px, not 2px.
-- **Rect rounding**: `rx="8"` for nodes, `rx="12"` for inner containers, `rx="16"` to `rx="20"` for outer containers.
-- **Connector paths**: MUST have `fill="none"`. SVG defaults to `fill: black` otherwise.
-
-### Arrow Marker
-
-Include this `<defs>` block at the start of **every** SVG:
-
-```xml
-<defs>
-  <marker id="arrow" viewBox="0 0 10 10" refX="8" refY="5"
-          markerWidth="6" markerHeight="6" orient="auto-start-reverse">
-    <path d="M2 1L8 5L2 9" fill="none" stroke="context-stroke"
-          stroke-width="1.5" stroke-linecap="round" stroke-linejoin="round"/>
-  </marker>
-</defs>
-```
-
-Use `marker-end="url(#arrow)"` on lines. The arrowhead inherits the line color via `context-stroke`.
-
-### CSS Classes (Provided by the Template)
-
-The template page provides:
-
-- Text: `.t`, `.ts`, `.th`
-- Neutral: `.box`, `.arr`, `.leader`, `.node`
-- Color ramps: `.c-purple`, `.c-teal`, `.c-coral`, `.c-pink`, `.c-gray`, `.c-blue`, `.c-green`, `.c-amber`, `.c-red` (all with automatic light/dark mode)
-
-You do **not** need to redefine these — just apply them in your SVG. The template file contains the full CSS definitions.
-
----
-
-## SVG Boilerplate
-
-Every SVG inside the template page starts with this exact structure:
-
-```xml
-<svg width="100%" viewBox="0 0 680 {HEIGHT}" xmlns="http://www.w3.org/2000/svg">
-  <defs>
-    <marker id="arrow" viewBox="0 0 10 10" refX="8" refY="5"
-            markerWidth="6" markerHeight="6" orient="auto-start-reverse">
-      <path d="M2 1L8 5L2 9" fill="none" stroke="context-stroke"
-            stroke-width="1.5" stroke-linecap="round" stroke-linejoin="round"/>
-    </marker>
-  </defs>
-
-  <!-- Diagram content here -->
-
-</svg>
-```
-
-Replace `{HEIGHT}` with the actual computed height (last element bottom + 40px).
-
-### Node Patterns
-
-**Single-line node (44px):**
-```xml
-<g class="node c-blue">
-  <rect x="100" y="20" width="180" height="44" rx="8" stroke-width="0.5"/>
-  <text class="th" x="190" y="42" text-anchor="middle" dominant-baseline="central">Service name</text>
-</g>
-```
-
-**Two-line node (56px):**
-```xml
-<g class="node c-teal">
-  <rect x="100" y="20" width="200" height="56" rx="8" stroke-width="0.5"/>
-  <text class="th" x="200" y="38" text-anchor="middle" dominant-baseline="central">Service name</text>
-  <text class="ts" x="200" y="56" text-anchor="middle" dominant-baseline="central">Short description</text>
-</g>
-```
-
-**Connector (no label):**
-```xml
-<line x1="200" y1="76" x2="200" y2="120" class="arr" marker-end="url(#arrow)"/>
-```
-
-**Container (dashed or solid):**
-```xml
-<g class="c-purple">
-  <rect x="40" y="92" width="600" height="300" rx="16" stroke-width="0.5"/>
-  <text class="th" x="66" y="116">Container label</text>
-  <text class="ts" x="66" y="134">Subtitle info</text>
-</g>
-```
-

-
-## Diagram Types
-
-Choose the layout that fits the subject:
-
-1. **Flowchart** — CI/CD pipelines, request lifecycles, approval workflows, data processing. Single-direction flow (top-down or left-right). Max 4-5 nodes per row.
-2. **Structural / Containment** — Cloud infrastructure nesting, system architecture with layers. Large outer containers with inner regions. Dashed rects for logical groupings.
-3. **API / Endpoint Map** — REST routes, GraphQL schemas. Tree from root, branching to resource groups, each containing endpoint nodes.
-4. **Microservice Topology** — Service mesh, event-driven systems. Services as nodes, arrows for communication patterns, message queues between.
-5. **Data Flow** — ETL pipelines, streaming architectures. Left-to-right flow from sources through processing to sinks.
-6. **Physical / Structural** — Vehicles, buildings, hardware, anatomy. Use shapes that match the physical form — `<path>` for curved bodies, `<polygon>` for tapered shapes, `<ellipse>`/`<circle>` for cylindrical parts, nested `<rect>` for compartments. See `references/physical-shape-cookbook.md`.
-7. **Infrastructure / Systems Integration** — Smart cities, IoT networks, multi-domain systems. Hub-spoke layout with central platform connecting subsystems. Semantic line styles (`.data-line`, `.power-line`, `.water-pipe`, `.road`). See `references/infrastructure-patterns.md`.
-8. **UI / Dashboard Mockups** — Admin panels, monitoring dashboards. Screen frame with nested chart/gauge/indicator elements. See `references/dashboard-patterns.md`.
-
-For physical, infrastructure, and dashboard diagrams, load the matching reference file before generating — each one provides ready-made CSS classes and shape primitives.
-
----
-
-## Validation Checklist
-
-Before finalizing any SVG, verify ALL of the following:
-
-1. Every `<text>` has class `t`, `ts`, or `th`.
-2. Every `<text>` inside a box has `dominant-baseline="central"`.
-3. Every connector `<path>` or `<line>` used as arrow has `fill="none"`.
-4. No arrow line crosses through an unrelated box.
-5. `box_width >= (longest_label_chars × 8) + 48` for 14px text.
-6. `box_width >= (longest_label_chars × 6.5) + 48` for 12px text.
-7. ViewBox height = bottom-most element + 40px.
-8. All content stays within x=40 to x=640.
-9. Color classes (`c-*`) are on `<g>` or shape elements, never on `<path>` connectors.
-10. Arrow `<defs>` block is present.
-11. No gradients, shadows, blur, or glow effects.
-12. Stroke width is 0.5px on all node borders.

-
-## Output & Preview
-
-### Default: standalone HTML file
-
-Write a single `.html` file the user can open directly. No server, no dependencies, works offline. Pattern:
-
-```python
-# 1. Load the template
-template = skill_view("concept-diagrams", "templates/template.html")
-
-# 2. Fill in title, subtitle, and paste your SVG
-html = template.replace(
-    "<!-- DIAGRAM TITLE HERE -->", "SN2 reaction mechanism"
-).replace(
-    "<!-- OPTIONAL SUBTITLE HERE -->", "Bimolecular nucleophilic substitution"
-).replace(
-    "<!-- PASTE SVG HERE -->", svg_content
-)
-
-# 3. Write to a user-chosen path (or ./ by default)
-write_file("./sn2-mechanism.html", html)
-```
-
-Tell the user how to open it:
-
-```
-# macOS
-open ./sn2-mechanism.html
-# Linux
-xdg-open ./sn2-mechanism.html
-```
-
-### Optional: local preview server (multi-diagram gallery)
-
-Only use this when the user explicitly wants a browsable gallery of multiple diagrams.
-
-**Rules:**
-- Bind to `127.0.0.1` only. Never `0.0.0.0`. Exposing diagrams on all network interfaces is a security hazard on shared networks.
-- Pick a free port (do NOT hard-code one) and tell the user the chosen URL.
-- The server is optional and opt-in — prefer the standalone HTML file first.
-
-Recommended pattern (lets the OS pick a free ephemeral port):
-
-```bash
-# Put each diagram in its own folder under .diagrams/
-mkdir -p .diagrams/sn2-mechanism
-# ...write .diagrams/sn2-mechanism/index.html...
-
-# Serve on loopback only, free port
-cd .diagrams && python3 -c "
-import http.server, socketserver
-with socketserver.TCPServer(('127.0.0.1', 0), http.server.SimpleHTTPRequestHandler) as s:
-    print(f'Serving at http://127.0.0.1:{s.server_address[1]}/')
-    s.serve_forever()
-" &
-```
-
-If the user insists on a fixed port, use `127.0.0.1:<port>` — still never `0.0.0.0`. Document how to stop the server (`kill %1` or `pkill -f "http.server"`).

-# Apartment Floor Plan: 3 BHK to 4 BHK Conversion
-
-An architectural floor plan showing a 1,500 sq ft apartment with proposed modifications to convert from 3 BHK to 4 BHK. Demonstrates architectural drawing conventions, room layouts, proposed changes with dotted lines, and area comparison tables.
-
-## Key Patterns Used
-
-- **Architectural floor plan**: Top-down view with walls, doors, windows
-- **Proposed modifications**: Dotted red lines for new walls
-- **Room color coding**: Light fills to distinguish room types
-- **Circulation paths**: Arrows showing new access routes
-- **Data table**: Before/after area comparison with highlighting
-- **Architectural symbols**: North arrow, scale bar, door swings
-
-## Diagram Type
-
-This is an **architectural floor plan** with:
-- **Plan view**: Top-down orthographic projection
-- **Overlay technique**: Existing structure + proposed changes
-- **Quantitative data**: Area measurements and comparison table

-## Layout Notes
-
-- **ViewBox**: 800×780 (portrait for floor plan + table)
-- **Scale**: 10px = 1 foot (apartment ~50ft × 33ft)
-- **Floor plan origin**: Offset at (50, 60) for margins
-- **Wall thickness**: 6px outer, 3px inner (represents ~6" walls)
-- **Room labels**: Centered in each room with area below
-- **Table placement**: Below floor plan with full width
-
-## Color Coding
-
-| Element | Color | Usage |
-|---------|-------|-------|
-| Proposed walls | Red (#A32D2D) dotted | New construction |
-| New room fill | Red 15% opacity | Bedroom 4 area |
-| Circulation | Green (#3B6D11) | New access path |
-| Window glass | Blue (#378ADD) | Glass indication |
-| Bedrooms | Purple/Teal/Amber tints | Room differentiation |
-| Wet areas | Blue tint | Bathrooms |
-| Living | Coral tint | Common areas |
-
-## When to Use This Pattern
-
-Use this diagram style for:
-- Apartment/house floor plans
-- Office layout planning
-- Renovation proposals showing before/after
-- Space planning with area calculations
-- Real estate marketing materials

-# Automated Password Reset Flow
-
-A two-section flowchart tracing the full user journey for a web application password reset: the initial request phase (forgot password → email check → token generation) and the reset-form phase (link click → new password entry → token/password validation). Demonstrates multi-exit decision diamonds, a three-column branching layout, a loop-back path, and a cross-section separator arrow.
-
-## Key Patterns Used
-
-- **Three-column layout**: Left column (error/terminal branches at cx=115), center column (main happy path at cx=340), right column (expired-token branch at cx=552) — allows side branches to live at the same y-level as center nodes without overlap
-- **Decision diamonds with `<polygon>`**: Each decision uses a `<g class="decision">` wrapper containing a `<polygon>` and centered `<text>`; the diamond points are computed as `cx±hw, cy±hh` (hw=100, hh=28)
-- **Pill-shaped terminals**: Start and end nodes use `rx=22` on their `<rect>` to signal entry/exit points; all mid-flow process nodes use `rx=8`
-- **Three-branch decision paths**: Each diamond has a "Yes" branch (down, short `<line>`) and a "No" branch (`<path>` going horizontal then vertical to a side column)
-- **Loop-back path**: Mismatch error node loops back to the password-entry node via a routing corridor at x=215 — a 5-px gap between the left column (right edge x=210) and center column (left edge x=220); the path exits the bottom of the error node, drops below it, travels right to x=215, then goes up to the target node's center y, then right 5 px into the node's left edge
-- **Section separator**: A dashed horizontal `<line>` at y=452 splits the two phases; the connecting arrow crosses it with a faded label ("user receives email") to preserve flow continuity
-- **Italic annotation**: The exact UX copy for the generic message ("If that email exists…") is shown as a faded italic `ts` text block below the left-branch terminal node
-- **Legend row**: Five inline swatches (gray, purple, teal, red, amber diamond) at the bottom explain the color-to-role mapping

-
-```css
-/* Decision diamond — amber fill, same palette as c-amber */
-.decision > polygon { fill: #FAEEDA; stroke: #854F0B; stroke-width: 0.5; }
-.decision > .th     { fill: #633806; }

-## Color Assignments
-
-| Element | Color | Reason |
-|---------|-------|--------|
-| Start / end terminals | `c-gray` | Neutral entry and exit points |
-| User actions (enter email, click link, enter password) | `c-gray` | User-facing steps with no system processing |
-| Generic message + request-handled terminal | `c-gray` | Intentionally neutral — the security message must not reveal data |
-| Generate & store token | `c-purple` | Backend system operations |
-| Send reset email | `c-teal` | Positive external action (outbound communication) |
-| Token expired error | `c-red` | Failure / blocking error state |
-| Password mismatch error | `c-red` | Validation failure |
-| Reset password + success | `c-teal` / `c-green` | Positive outcome: teal for the action, green pill for the terminal |
-| Decision diamonds | `c-amber` (custom `.decision`) | Warning / branch point — matches amber semantic meaning |

-## Layout Notes
-
-- **ViewBox**: 680×960 — tall flowchart with two phases
-- **Three-column structure**: Left (cx=115), center (cx=340), right (cx=552) — each branch stays within its column; only `<path>` arrows cross column boundaries
-- **Diamond formula**: `<polygon points="cx,cy-hh cx+hw,cy cx,cy+hh cx-hw,cy"/>` with hw=100, hh=28 gives a 200×56px diamond that sits flush with the center column (x=220–460)
-- **Branch routing pattern**: "No" paths use `<path d="M left_point,cy L side_cx,cy L side_cx,node_top">` — one horizontal segment + one vertical segment, no curves needed
-- **Loop corridor**: The 5-px gap at x=210–220 between left and center columns provides a clean vertical channel for the loop-back path without any node overlap; the path exits node bottom, drops 20px, goes right to x=215, climbs to target y, enters from left
-- **Section separator**: A dashed `<line>` at y=452 with `stroke-dasharray="8 5"` provides a visual phase break; the single connecting arrow crosses it at center, with a faded label on the arrow
-- **Pill terminals**: `rx=22` (half the 44px node height) produces a perfect capsule/pill shape — use this consistently for all start/end terminals
-- **Error annotation**: The exact UX copy is rendered as faded (`opacity=".45"`) italic `ts` text below the relevant node, keeping it informative without cluttering the flow

-# Autonomous LLM Research Agent Flow
-
-A multi-section flowchart showing Karpathy's autoresearch framework: human-agent handoff, the autonomous experiment loop with keep/discard decision branching, and the modifiable training pipeline. Demonstrates loop-back arrows, convergent decision paths, and semantic color coding for outcomes.
-
-## Key Patterns Used
-
-- **Three-section layout**: Setup row, main loop container, and detail container — each visually distinct
-- **Neutral dashed containers**: Loop and training pipeline use `var(--bg-secondary)` fill with dashed borders to recede behind colored content nodes
-- **Decision branching with convergence**: "val_bpb improved?" splits into Keep (green) and Discard (red), then both converge back to "Log to results.tsv"
-- **Loop-back arrow**: Dashed path with rounded corners on the right side of the container showing infinite repetition
-- **Semantic color for outcomes**: Green = improvement (keep), Red = no improvement (discard) — not arbitrary decoration
-- **Highlighted key step**: "Run training" uses `c-coral` to visually distinguish the most important step from other `c-teal` actions
-- **Horizontal pipeline flow**: Training details section uses left-to-right arrow-connected nodes (GPT → MuonAdamW → Evaluation)
-- **Footer metadata**: Fixed constraints shown as subtle centered text below the pipeline nodes
-- **Legend row**: Color key at the bottom explaining what each color means

-| Element | Color | Reason |
-|---------|-------|--------|
-| Human, program.md | `c-gray` | Neutral setup / input nodes |
-| AI agent | `c-purple` | The active intelligent actor |
-| Loop action steps | `c-teal` | Agent's analytical/editing actions |
-| Run training | `c-coral` | Highlighted key step — the 5-min training run |
-| Decision check | `c-gray` | Neutral evaluation checkpoint |
-| Keep (improved) | `c-green` | Semantic success — val_bpb decreased |
-| Discard (not improved) | `c-red` | Semantic failure — no improvement |
-| Training pipeline nodes | `c-coral` | Training infrastructure components |
-| Evaluation node | `c-amber` | Distinct from training — measurement/metric role |
-| Containers | Neutral (dashed) | Subtle grouping that recedes behind content |

-## Layout Notes
-
-- **ViewBox**: 680×920 (standard width, tall for 3 sections)
-- **Three sections**: Setup row (y=30–98), loop container (y=142–670), training details (y=710–880)
-- **Container style**: Dashed border (`stroke-dasharray="6 4"`), neutral fill (`var(--bg-secondary)`), `stroke-width="1"` — not colored, so inner nodes pop
-- **Loop-back arrow**: Dashed `<path>` with quadratic curves (`Q`) at corners for smooth rounded turns, running up the right side of the loop container from "Log" back to "Read code"
-- **Decision pattern**: Single question node ("val_bpb improved?") with diagonal arrows to Keep/Discard, then convergent diagonal arrows back to "Log to results.tsv"
-- **Decision labels**: "yes"/"no" labels placed along the diagonal arrows with `opacity=".6"` to stay subtle
-- **Key step highlight**: "Run training" uses `c-coral` while surrounding steps use `c-teal`, drawing the eye to the most important step
-- **Horizontal sub-flow**: Training pipeline uses left-to-right arrow-connected nodes (GPT model → MuonAdamW → Evaluation)
-- **Footer metadata**: Fixed constraints (data, vocab, budget, context) shown as a single centered `ts` text line with `opacity=".5"`
-- **Legend**: Four color swatches at the bottom explaining the semantic meaning of each color used

-# Journey of a Banana: From Tree to Smoothie
-
-A narrative journey diagram following a single banana across 3,000 miles and 3 weeks, from harvest in Costa Rica to a smoothie in the consumer's kitchen. Demonstrates storytelling through visualization, winding path layout, and progressive state changes.
-
-## Key Patterns Used
-
-- **Winding journey path**: S-curve connecting all stages visually
-- **Location markers**: Country flags and place names for geographic context
-- **Progressive state changes**: Banana color changes (green → yellow → brown → frozen → smoothie)
-- **Narrative details**: Fun elements like spider check, stickers, price tags
-- **Timeline**: Bottom timeline showing duration of journey
-- **Environmental context**: Ocean waves, gas clouds, store awning

-## Layout Notes
-
-- **ViewBox**: 850×680 (tall for winding path)
-- **Path style**: S-curve winding path connects all 7 stages
-- **Location labels**: Country flags + place names anchor geographic context
-- **State progression**: Same object (banana) shown in different states throughout
-- **Timeline**: Horizontal timeline at bottom shows journey duration
-- **Narrative elements**: Fun details (spider, stickers, price tags) add storytelling value
-- **Environmental context**: Ocean waves, gas clouds, awnings create sense of place

-# Commercial Aircraft Structure
-
-A physical/structural diagram showing an aircraft side profile using appropriate SVG shapes beyond rectangles - paths, polygons, ellipses for realistic representation.
-
-## Key Patterns Used
-
-- **Path elements**: Curved fuselage body with nose cone using quadratic bezier curves
-- **Polygon elements**: Tapered wing shape, triangular stabilizers, control surfaces
-- **Ellipse elements**: Engines (cylinders), wheels (circles)
-- **Line elements**: Landing gear struts, leader lines for labels
-- **Dashed strokes**: Interior sections (fuel tank), movable control surfaces (rudder, elevator)
-- **Layered composition**: Cabin sections drawn inside the fuselage shape
-- **Leader lines with labels**: Connect labels to components they describe

-## Shape Selection Guide
-
-| Physical form | SVG element | Example |
-|---------------|-------------|---------|
-| Curved body | `<path>` with Q (quadratic) or C (cubic) curves | Fuselage, nose cone |
-| Tapered/angular | `<polygon>` | Wings, stabilizers |
-| Cylindrical | `<ellipse>` | Engines, wheels, tanks |
-| Linear structure | `<line>` | Struts, pylons, gear legs |
-| Internal sections | `<rect>` inside parent shape | Cabin classes |
-| Dashed boundaries | `stroke-dasharray` on any shape | Fuel tanks, control surfaces |
-
-## Layout Notes
-
-- **ViewBox**: 680×400 (wider aspect ratio suits side profile)
-- **Layering**: Draw outer structures first, then interior details on top
-- **Leader lines**: Use `.leader` class (dashed) to connect labels to components
-- **Text sizes**: Use `.tl` (10px) for component labels, `.ts` (12px) for section labels
-- **Semantic colors**: Group by system (structure=blue, propulsion=coral, fuel=amber, etc.)

-# Out-of-Order CPU Core Microarchitecture
-
-A structural diagram showing the internal pipeline stages of a modern superscalar out-of-order CPU core. Demonstrates multi-stage vertical flow with parallel paths, fan-out patterns for execution ports, and a separate memory hierarchy sidebar.
-
-## Key Patterns Used
-
-- **Multi-stage vertical flow**: Six pipeline stages (Front End → Rename → Schedule → Execute → Retire)
-- **Parallel decode paths**: Main decode and µop cache bypass (dashed line for cache hit)
-- **Container grouping**: Logical stages grouped in colored containers
-- **Fan-out pattern**: Single scheduler dispatching to 6 execution ports
-- **Sidebar layout**: Memory hierarchy placed in separate column on right
-- **Stage labels**: Left-aligned labels indicating pipeline phase
-- **Color-coded semantics**: Different colors for each functional unit category
-
-## Diagram Type
-
-This is a **hybrid structural/flow** diagram:
-- **Flow aspect**: Instructions move top-to-bottom through pipeline stages
-- **Structural aspect**: Components are grouped by function (rename unit, execution cluster)
-- **Sidebar**: Memory hierarchy is architecturally separate but connected via data paths
-
-## Pipeline Stage Breakdown
-
-### Front End (Purple)
-```xml
-<!-- Fetch Unit -->
-<g class="node c-purple">
-  <rect x="40" y="70" width="140" height="56" rx="8" stroke-width="0.5"/>
-  <text class="th" x="110" y="90" text-anchor="middle" dominant-baseline="central">Fetch unit</text>

-<!-- Decode -->
-<g class="node c-purple">

-  <text class="ts" x="310" y="110" text-anchor="middle" dominant-baseline="central">x86 → µops, 6-wide</text>
-</g>
-```
-
-### µop Cache Bypass Path (Teal)
-The µop cache (Decoded Stream Buffer) provides an alternate path that bypasses the complex decoder:
-
-```xml
-<!-- µop Cache parallel to decode -->
-<g class="node c-teal">
-  <rect x="230" y="150" width="160" height="50" rx="8" stroke-width="0.5"/>
-  <text class="th" x="310" y="168" text-anchor="middle" dominant-baseline="central">µop cache (DSB)</text>
-  <text class="ts" x="310" y="186" text-anchor="middle" dominant-baseline="central">4K entries, 8-wide</text>
-</g>
-
-<!-- Dashed bypass path indicating cache hit -->
-<path d="M180 110 L205 110 L205 175 L230 175" fill="none" class="arr" 
-      stroke-dasharray="4 3" marker-end="url(#arrow)"/>
-<text class="tx" x="164" y="148" opacity=".6">hit</text>
-```
-
-### Rename/Allocate Container (Coral)
-Groups related rename components in a container:
-
-```xml
-<!-- Outer container -->
-<g class="c-coral">
-  <rect x="40" y="250" width="530" height="130" rx="12" stroke-width="0.5"/>
-  <text class="th" x="60" y="274">Rename / allocate</text>
-  <text class="ts" x="60" y="292">Map architectural → physical registers</text>
-</g>
-
-<!-- Inner components -->
-<g class="node c-coral">
-  <rect x="60" y="310" width="180" height="56" rx="8" stroke-width="0.5"/>
-  <text class="th" x="150" y="330" text-anchor="middle" dominant-baseline="central">Register alias table</text>
-  <text class="ts" x="150" y="350" text-anchor="middle" dominant-baseline="central">180 physical regs</text>
-</g>
-```
-
-### Scheduler Fan-Out Pattern (Amber → Teal)
-Single unified scheduler dispatching to multiple execution ports:
-
-```xml
-<!-- Unified Scheduler -->
-<g class="node c-amber">
-  <rect x="140" y="420" width="330" height="50" rx="8" stroke-width="0.5"/>

-  <text class="ts" x="305" y="456" text-anchor="middle" dominant-baseline="central">97 entries, out-of-order dispatch</text>
-</g>
-
-<!-- Fan-out arrows to 6 ports -->
-<line x1="170" y1="470" x2="90" y2="540" class="arr" marker-end="url(#arrow)"/>
-<line x1="215" y1="470" x2="170" y2="540" class="arr" marker-end="url(#arrow)"/>

-<line x1="420" y1="470" x2="490" y2="540" class="arr" marker-end="url(#arrow)"/>
-```
-
-### Execution Port Box Pattern
-Compact boxes showing port number and capabilities:
-
-```xml
-<!-- Execution port with multi-line capability -->
-<g class="node c-teal">
-  <rect x="55" y="540" width="70" height="64" rx="6" stroke-width="0.5"/>

-
-### Reorder Buffer (Pink)
-Wide horizontal bar at bottom showing retirement:
-
-```xml
-<g class="c-pink">

-```
-
-### Memory Hierarchy Sidebar (Blue)
-Separate column showing cache levels:
-
-```xml
-<!-- Container -->
-<g class="c-blue">
-  <rect x="600" y="30" width="190" height="360" rx="16" stroke-width="0.5"/>

-  <text class="th" x="695" y="88" text-anchor="middle" dominant-baseline="central">L1-I cache</text>
-  <text class="ts" x="695" y="106" text-anchor="middle" dominant-baseline="central">32 KB, 8-way</text>
-</g>
-<!-- Additional levels follow same pattern -->
-```
-
-## Connection Patterns
-
-### Instruction Fetch Path
-Horizontal arrow from L1-I cache to fetch unit:
-```xml
-<path d="M620 95 L200 95" fill="none" class="arr" marker-end="url(#arrow)"/>
-<text class="tx" x="410" y="88" text-anchor="middle" opacity=".6">instruction fetch</text>
-```
-
-### Load/Store Path
-Complex path from execution ports to L1-D cache:
-```xml
-<path d="M250 604 L250 640 L580 640 L580 160 L620 160" fill="none" class="arr" marker-end="url(#arrow)"/>
-<text class="tx" x="415" y="652" text-anchor="middle" opacity=".6">load / store</text>
-```
-
-### Commit Path (dashed)
-Dashed line showing write-back from ROB to register file:
-```xml
-<path d="M550 690 L580 690 L580 445 L595 445" fill="none" class="arr" stroke-dasharray="4 3"/>
-<text class="tx" x="590" y="578" opacity=".6" transform="rotate(-90 590 578)">commit</text>
-```
-
-### Path Merge (Decode + µop Cache)
-Two paths converging before rename:
-```xml
-<line x1="390" y1="98" x2="430" y2="98" class="arr"/>
-<line x1="390" y1="175" x2="430" y2="175" class="arr"/>
-<path d="M430 98 L430 175" fill="none" stroke="var(--text-secondary)" stroke-width="1.5"/>
-<line x1="430" y1="136" x2="470" y2="136" class="arr" marker-end="url(#arrow)"/>
-```
-
-## Text Classes
-
-This diagram uses an additional text class for very small labels:
-
-```css
-.tx { font-family: system-ui, -apple-system, sans-serif; font-size: 10px; fill: var(--text-secondary); }
-```
-
-Used for:
-- Execution port capability labels (ALU, Branch, Load, etc.)
-- Connection labels (instruction fetch, load/store, commit)
-- DRAM latency annotation
-
-## Color Semantic Mapping
-
-| Color | Stage | Components |
-|-------|-------|------------|
-| `c-purple` | Front end | Fetch, Branch predictor, Decode |
-| `c-teal` | Execution | µop cache, Execution ports |
-| `c-coral` | Rename | RAT, Physical RF, Free list |
-| `c-amber` | Schedule | Unified scheduler |
-| `c-pink` | Retire | Reorder buffer |
-| `c-blue` | Memory | L1-I, L1-D, L2, DRAM |
-| `c-gray` | External | Off-chip DRAM |
-
-## Layout Notes
-
-- **ViewBox**: 820×720 (taller than wide for vertical pipeline flow)
-- **Main pipeline**: x=40 to x=570 (530px width)
-- **Memory sidebar**: x=600 to x=790 (190px width)
-- **Stage labels**: x=30, left-aligned, 50% opacity
-- **Vertical spacing**: ~80-100px between major stages
-- **Container padding**: 20px inside containers
-- **Port spacing**: 80px between execution port centers
-- **Legend**: Bottom-right of memory sidebar, explains color coding
-
-## Architectural Details Shown
-
-| Component | Specification | Notes |
-|-----------|---------------|-------|
-| Fetch | 6-wide, 32B/cycle | Typical modern Intel/AMD |

-| L1-I | 32 KB, 8-way | Instruction cache |
-| L1-D | 48 KB, 12-way | Data cache |
-| L2 | 1.25 MB, 20-way | Unified |
-| DRAM | DDR5-6400, ~80ns | Off-chip |

-# Electricity Grid: Generation to Consumption
-
-A left-to-right flow diagram showing electricity from multiple generation sources through transmission and distribution networks to end consumers. Demonstrates multi-stage flow layout, voltage level visual hierarchy, and smart grid data overlay.
-
-## Key Patterns Used
-
-- **Multi-stage horizontal flow**: Four distinct columns (Generation → Transmission → Distribution → Consumption)
-- **Stage dividers**: Vertical dashed lines separating each phase
-- **Voltage level hierarchy**: Different line weights/colors for HV, MV, LV
-- **Smart grid data overlay**: Dashed data flow lines from control center
-- **Capacity labels**: Power ratings on generation sources
-- **Multiple source convergence**: Four generators feeding into single transmission grid

-# Feature Film Production Pipeline
-
-A phased workflow showing the five stages of filmmaking, using containers with inner nodes and horizontal sub-flows within a phase.
-
-## Key Patterns Used
-
-- **Phase containers**: Large rounded rectangles with neutral background and dashed borders
-- **Inner task nodes**: Smaller colored nodes inside containers for sub-tasks
-- **Horizontal flow within container**: Post-production shows sequential pipeline with arrows (Editing → Color → VFX → Sound → Score)
-- **Consistent phase spacing**: ~30px gap between phase containers
-- **Phase labels with subtitles**: Each container has title + description

-## Color Assignments
-
-| Element | Color | Reason |
-|---------|-------|--------|
-| Phase containers | Neutral (dashed) | Subtle grouping, doesn't compete with content |
-| Development tasks | `c-purple` | Creative/concept work |
-| Pre-production tasks | `c-teal` | Planning and preparation |
-| Production tasks | `c-coral` | Active filming (main event) |
-| Post-production tasks | `c-amber` | Processing/refinement |
-| Distribution tasks | `c-blue` | Outward delivery/release |
-
-## Layout Notes
-
-- **ViewBox**: 680×780 (standard width, tall for 5 phases)
-- **Container style**: Dashed border (`stroke-dasharray="6 4"`), neutral fill (`var(--bg-secondary)`), `stroke-width="1"`
-- **Container height**: 110px for 3-node phases, 150px for post-production (more complex)
-- **Inner node dimensions**: 160×36px for standard tasks, variable width for post-production sequential flow
-- **Phase gap**: 30px between containers
-- **Horizontal sub-flow**: Post-production uses tightly packed nodes with arrows between them to show sequence
-- **Convergence node**: "Final master / DCP" sits below the horizontal flow, collecting all post outputs

-# Hospital Emergency Department Flow
-
-A multi-path flowchart showing patient journey through an emergency department with priority-based routing using semantic colors (red=critical, amber=urgent, green=stable).
-
-## Key Patterns Used
-
-- **Semantic color coding**: Red/amber/green for priority levels (not arbitrary decoration)
-- **Stage labels**: Left-aligned faded labels marking workflow phases
-- **Convergent paths**: Multiple entry points merging, then branching, then converging again
-- **Nested containers**: Diagnostics grouped in a container with inner nodes
-- **Legend**: Color key at bottom explaining priority levels

-# ML Benchmark Grouped Bar Chart with Dual Axis
-
-A quantitative data visualization comparing LLM inference speed across quantization levels with dual Y-axes, threshold markers, and an inset accuracy table.
-
-## Key Patterns Used
-
-- **Grouped bars**: Min/max range pairs per category using semantic color pairs (lighter=min, darker=max)
-- **Dual Y-axis**: Left axis for primary metric (tok/s), right axis for secondary metric (VRAM GB)
-- **Overlay line graph**: `<polyline>` with labeled dots showing VRAM usage across categories
-- **Threshold marker**: Dashed red horizontal line indicating hardware limit (24 GB GPU)
-- **Zone annotations**: Subtle text labels above/below threshold for context
-- **Inset data table**: Alternating row fills below chart with quantitative accuracy data
-- **Semantic color coding**: Each quantization level gets its own color from the skill palette (red=OOM, amber=slow, teal=sweet spot, blue=fast)
-
-## Diagram Type
-
-This is a **quantitative data chart** with:
-- **Grouped vertical bars**: Range bars showing min–max performance per category
-- **Secondary axis line**: VRAM usage overlaid as a connected scatter plot
-- **Threshold annotation**: Hardware constraint line
-- **Inset table**: Supporting accuracy metrics
-
-## Chart Layout Formula
-
-```
-Chart area:  x=90–590, y=70–410 (500px wide, 340px tall)
-Left Y-axis: Primary metric (tok/s)
-             y = 410 − (val / max_val) × 340
-Right Y-axis: Secondary metric (VRAM GB)
-              Same formula, different scale labels
-Groups:       Divide width by number of categories
-Bars:         Each group → min bar (34px) + 8px gap + max bar (34px)
-Line overlay: <polyline> connecting data points across group centers
-Threshold:    Horizontal dashed line at critical value
-Table:        Below chart, alternating row fills
-```
-
-## Data Mapped
-
-| Quantization | Model Size | Speed (tok/s) | VRAM (GB) | MMLU Pro | Status |
-|-------------|-----------|---------------|-----------|----------|--------|
-| FP16 | 62 GB | 0.5–2 | 62 | 75.2 | OOM / unusable |
-| Q8_0 | 32 GB | 3–5 | 32 | 75.0 | Partial offload |
-| Q4_K_M | 16.8 GB | 8–12 | 16.8 | 73.1 | Fits in VRAM ✓ |
-| IQ3_M | 12 GB | 12–15 | 12 | 70.5 | Full GPU speed |

-
-## When to Use This Pattern
-
-Use this diagram style for:
-- Model benchmark comparisons across quantization levels
-- Performance vs. resource usage tradeoff analysis
-- Any multi-metric comparison with a hardware/software constraint
-- GPU/TPU/accelerator benchmarking dashboards
-- Accuracy vs. speed Pareto frontiers
-- Hardware requirement sizing charts

-# Place Order — UML Sequence Diagram
-
-A UML sequence diagram for the 'Place Order' use case in an e-commerce system. Six lifelines (:Customer, :ShoppingCart, :OrderController, :PaymentGateway, :InventorySystem, :EmailService) interact across 14 numbered messages. An **alt** combined fragment (amber) covers the three conditional outcomes — payment authorized, payment failed, and item unavailable. A **par** combined fragment (teal) nested inside the success branch shows concurrent email confirmation and stock-level update. Demonstrates activation bars, two distinct arrowhead types, UML pentagon fragment tags, and guard conditions.
-
-## Key Patterns Used
-
-- **6 lifelines at equal spacing**: Lifeline centers placed at x=90, 190, 290, 390, 490, 590 (100px apart) so the first box left-edge lands at x=40 and the last right-edge lands at x=640 — exactly filling the safe area
-- **Two-row actor headers**: Each lifeline box shows `":"` (small, tertiary color) on one line and the class name (slightly larger, bold) on a second line, matching the UML anonymous-instance notation `:ClassName`
-- **Two separate arrowhead markers**: `#arr-call` is a filled triangle (`<polygon>`) for synchronous calls; `#arr-ret` is an open chevron (`fill="none"`) for dashed return messages — both use `context-stroke` to inherit line color
-- **Activation bars**: Narrow 8px-wide rectangles (`class="activation"`) layered on top of lifeline stems to show object execution periods; OrderController's bar spans the entire interaction; shorter bars mark PaymentGateway, InventorySystem, and EmailService during their active windows
-- **Combined fragment pentagon tag**: Each `alt` / `par` frame uses a `<polygon>` dog-eared label shape in the top-left corner — points follow the pattern `(x,y) (x+w,y) (x+w+6,y+6) (x+w+6,y+18) (x,y+18)` creating the characteristic UML notch
-- **Nested par inside alt**: The `par` rect (teal) sits inside branch 1 of the `alt` rect (amber); inner rect uses inset x/y (+15/+2) so both borders remain visible and distinguishable
-- **Guard conditions**: Italic text in `[square brackets]` placed immediately after each alt frame divider line, or just inside the top frame for branch 1 — rendered with a dedicated `guard-lbl` class (italic, amber color)
-- **Alt branch dividers**: Solid horizontal lines (`.frag-alt-div`) span the full alt rect width to separate the three branches; par branch separator uses a dashed line (`.frag-par-div`) per UML spec
-- **Lifeline end caps**: Short 14px horizontal tick marks at y=590 (bottom of all lifeline stems) to formally terminate each lifeline
-- **Message sequence annotation**: A faint counter row below the legend (①–③ / ④–⑩ / ⑪–⑫ / ⑬–⑭) explains the four message groups without adding noise to the diagram body

-## Color Assignments
-
-| Element | Color | Reason |
-|---------|-------|--------|
-| Actor header boxes | Neutral (`var(--bg-secondary)`) | Structural / non-semantic — all lifelines share one style |
-| Activation bars | Neutral (`var(--bg-secondary)`) | Show execution periods without adding semantic color |
-| Synchronous call arrows | `var(--text-primary)` + filled triangle | High contrast for calls — the primary interaction direction |
-| Return / dashed arrows | `var(--text-secondary)` + open chevron | Lower contrast for returns — secondary flow direction |
-| `alt` fragment | Amber (`#FAEEDA` / `#854F0B`) | Warning / conditional — matches `c-amber` semantic meaning |
-| Guard condition text | Amber italic | Belongs visually to the alt fragment |
-| `par` fragment | Teal (`#E1F5EE` / `#0F6E56`) | Concurrent success path — matches `c-teal` semantic meaning |
-| Alt branch dividers | Amber solid line | Continuity with the alt frame color |
-| Par branch divider | Teal dashed line | UML spec: par branches separated by dashed lines |
-
-## Layout Notes
-
-- **ViewBox**: 680×648 (standard width; height = lifeline bottom y=590 + legend + annotation + 16px buffer)
-- **Lifeline spacing formula**: `(safe_area_width) / (n_lifelines − 1) = 600 / 5 = 120px` — but use `spacing = 100px` starting at `x=90` so that first box left = 40 and last box right = 640 exactly
-- **Actor box split-label trick**: Two separate `<text>` elements per box — one for `":"` (10px, tertiary color) and one for the class name (11.5px bold, primary color) — avoids the 14px font needing ~150px+ per box for long names like "OrderController"
-- **Pentagon tag formula**: For a fragment starting at `(fx, fy)`, the tag polygon points are `(fx,fy) (fx+w,fy) (fx+w+6,fy+6) (fx+w+6,fy+18) (fx,fy+18)` where `w` = approximate text width of the keyword + 8px padding each side
-- **Nested fragment inset**: The `par` rect uses `x = alt_x + 15` and `y = alt_y_current + 2` so both borders remain simultaneously visible — inset enough to separate visually, not so much that it wastes vertical space
-- **Activation bar placement**: `x = lifeline_cx − 4`, `width = 8` — centered on the lifeline and narrow enough not to obscure the dashed stem behind it
-- **Message label y-offset**: All labels are placed at `y = arrow_y − 5` to sit just above the arrow line; this applies to both left-going and right-going arrows since `text-anchor="middle"` handles horizontal centering automatically
-- **Return arrows entering activation bars**: End `x1/x2` at lifeline center (e.g. x=294 for OrderController) rather than the bar edge (x=286) — the small overlap is intentional and clarifies the target object
-- **Alt guard label placement**: Branch 1 guard goes at `y = frame_top + 13` to the right of the pentagon tag; subsequent branch guards go at `divider_y + 14` so they sit just inside the new branch
-- **Lifeline end cap pattern**: `<line x1="cx−7" y1="590" x2="cx+7" y2="590" stroke-width="1.5"/>` — a simple symmetric tick, no special marker needed

-# Smart City Infrastructure
-
-A multi-system integration diagram showing interconnected city infrastructure (power, water, transport) connected through a central IoT platform with a citizen dashboard on top. Demonstrates hub-spoke layout, diverse physical shapes, and UI mockups.
-
-## Key Patterns Used
-
-- **Hub-spoke layout**: Central IoT platform with radiating data connections to subsystems
-- **Connection dots**: Visual indicators where data lines attach to the central hub
-- **Dashboard/UI mockup**: Screen with mini-charts, gauges, and status indicators
-- **Multi-system integration**: Three independent systems unified by central platform
-- **Semantic line styles**: Different stroke styles for data (dashed), power, water, roads
-- **Physical infrastructure shapes**: Solar panels, wind turbines, dams, pipes, roads, vehicles

-## Layout Notes
-
-- **ViewBox**: 720×620 (wider for three-column system layout)
-- **Hub position**: Central IoT at (360, 270) - geometric center
-- **Data lines**: Use quadratic curves or L-shaped paths, add connection dots at hub attachment points
-- **System spacing**: ~200px width per system section
-- **Vertical layers**: Dashboard (top) → IoT Hub (middle) → Systems (bottom)
-- **Component grouping**: Use `<g transform="translate(x,y)">` for each major component for easy positioning

-# Smartphone Layer Anatomy
-
-An exploded view diagram showing all internal layers of a smartphone from front glass to back, with alternating left/right labels to avoid overlap. Demonstrates layered product teardown visualization and component detail.
-
-## Key Patterns Used
-
-- **Exploded vertical stack**: Layers separated vertically to show internal structure
-- **Alternating labels**: Left/right label placement prevents text overlap
-- **Component detail**: Chips, coils, lenses rendered with realistic shapes
-- **Thickness scale**: Measurement indicator on the side
-- **Progressive depth**: Each layer slightly offset to create 3D stack effect

-# Modern Onshore Wind Turbine Structure
-
-A physical/structural cross-section diagram showing all major components of a modern wind turbine from underground foundation to blade tips.
-
-## Key Patterns Used
-
-- **Underground section**: Soil layers, deep concrete foundation with rebar reinforcement grid, spread footing
-- **Cross-section view**: Tower wall thickness shown, internal components visible
-- **Tapered tower**: Path elements creating realistic tower silhouette that narrows toward top
-- **Internal access**: Ladder with rungs, elevator shaft inside tower
-- **Cable routing**: Power cables running from nacelle down through tower to transformer
-- **Nacelle cutaway**: Gearbox, generator, brake, yaw system all visible inside housing
-- **Rotor assembly**: Hub with pitch motors at blade roots, three composite blades with gradient fill
-- **Ground level marker**: Clear separation between above/below ground
-- **Component color coding**: Each system type has distinct color (blue=generator, gold=gearbox, red=brake, green=yaw, purple=pitch)
-- **Legend bar**: Quick reference for color meanings

-# Dashboard Patterns
-
-Building blocks for UI/dashboard mockups inside a concept diagram — admin panels, monitoring dashboards, control interfaces, status displays.
-
-## Pattern
-
-A "screen" is a rounded dark rect inside a lighter "frame" rect, with chart/gauge/indicator elements nested on top.
-
-```xml
-<!-- Monitor frame -->
-<rect class="dashboard" x="0" y="0" width="200" height="120" rx="8"/>
-<!-- Screen -->
-<rect class="screen" x="10" y="10" width="180" height="85" rx="4"/>
-<!-- Mini bar chart -->
-<rect class="screen-content" x="18" y="18" width="50" height="35" rx="2"/>
-<rect class="screen-chart" x="22" y="38" width="8" height="12"/>
-<rect class="screen-chart" x="33" y="32" width="8" height="18"/>
-<!-- Gauge -->
-<circle class="screen-bar" cx="100" cy="35" r="12"/>
-<text x="100" y="39" text-anchor="middle" fill="#E8E6DE" style="font-size:8px">78%</text>
-<!-- Status indicators -->
-<circle cx="35" cy="74" r="6" fill="#97C459"/> <!-- green = ok -->
-<circle cx="75" cy="74" r="6" fill="#EF9F27"/> <!-- amber = warning -->
-<circle cx="115" cy="74" r="6" fill="#E24B4A"/> <!-- red = alert -->
-```
-
-## CSS
-

-## Tips
-
-- Dashboard screens stay dark in both light and dark mode — they represent actual monitor glass.
-- Keep on-screen text small (`font-size:8px` or `10px`) and high-contrast (near-white fill on dark).
-- Use the status triad green/amber/red consistently — OK / warning / alert.
-- A single dashboard usually sits on top of an infrastructure hub diagram as a unified view (see `examples/smart-city-infrastructure.md`).

-# Infrastructure Patterns
-
-Reusable shapes and line styles for infrastructure / systems-integration diagrams (smart cities, IoT networks, industrial systems, multi-domain architectures).
-
-## Layout pattern: hub-spoke
-
-- **Central hub**: Hexagon or circle representing the integration platform
-- **Radiating connections**: Data lines from hub to each subsystem with connection dots
-- **Subsystem sections**: Each system (power, water, transport) in its own region
-- **Dashboard on top**: Optional UI mockup showing a unified view (see `dashboard-patterns.md`)
-
-```xml
-<!-- Central hub (hexagon) -->
-<polygon class="iot-hex" points="0,-45 39,-22 39,22 0,45 -39,22 -39,-22"/>
-
-<!-- Data lines with connection dots -->
-<path class="data-line" d="M 321 248 L 200 248 L 120 380" stroke-dasharray="4 3"/>
-<circle cx="321" cy="248" r="4" fill="#7F77DD"/>
-```
-
-## Semantic line styles
-
-Use a dedicated CSS class per subsystem so every diagram reads the same way:
-
-```css
-.data-line  { stroke: #7F77DD; stroke-width: 2; fill: none; stroke-dasharray: 4 3; }
-.power-line { stroke: #EF9F27; stroke-width: 2; fill: none; }
-.water-pipe { stroke: #378ADD; stroke-width: 4; stroke-linecap: round; fill: none; }
-.road       { stroke: #888780; stroke-width: 8; stroke-linecap: round; fill: none; }

-# Physical Shape Cookbook
-
-Guidance for drawing physical objects (vehicles, buildings, hardware, mechanical systems, anatomy) — when rectangles aren't enough.
-
-## Shape selection
-
-| Physical form | SVG element | Example use |
-|---------------|-------------|-------------|
-| Curved bodies | `<path>` with Q/C curves | Fuselage, tanks, pipes |
-| Tapered/angular shapes | `<polygon>` | Wings, fins, wedges |
-| Cylindrical/round | `<ellipse>`, `<circle>` | Engines, wheels, buttons |
-| Linear structures | `<line>` | Struts, beams, connections |
-| Internal sections | `<rect>` inside parent | Compartments, rooms |
-| Dashed boundaries | `stroke-dasharray` | Hidden parts, fuel tanks |
-
-## Layering approach
-
-1. Draw outer structure first (fuselage, frame, hull)
-2. Add internal sections on top (cabins, compartments)
-3. Add detail elements (engines, wheels, controls)
-4. Add leader lines with labels
-
-## Semantic CSS classes (instead of c-* ramps)
-
-For physical diagrams, define component-specific classes directly rather than applying `c-*` color classes. This makes each part self-documenting and lets you keep a restrained palette:
-
-```css
-.fuselage { fill: #F1EFE8; stroke: #5F5E5A; stroke-width: 1; }
-.wing     { fill: #E6F1FB; stroke: #185FA5; stroke-width: 1; }
-.engine   { fill: #FAECE7; stroke: #993C1D; stroke-width: 1; }
-```
-
-Add these to a local `<style>` inside the SVG (or extend the host page's `<style>` block). The light-mode/dark-mode pattern still works — use the CSS variables from the template (`var(--bg-secondary)`, `var(--border)`, `var(--text-primary)`) if you want dark-mode awareness.
-
-## Reference examples
-
-Look at these example files for working physical-diagram patterns:
-
-- `examples/commercial-aircraft-structure.md` — fuselage curves + tapered wings + ellipse engines
-- `examples/wind-turbine-structure.md` — underground foundation, tubular tower, nacelle cutaway
-- `examples/smartphone-layer-anatomy.md` — exploded-view stack with alternating labels
-- `examples/apartment-floor-plan-conversion.md` — walls, doors, windows, proposed changes
