Three-column Sankey diagram (Income → Categories → Tags) rendered with

interpolate color from source to destination nodes, neon glow effects
on nodes and bands, and a surplus node when income exceeds expenses.

units from px to pt, preventing Qt delegate code from receiving -1
point sizes during inline cell editing.
