/* ============================================================
   Coin Jar — design tokens

   Chart colours come from the validated data-viz palette:
   a single blue hue for every quantitative mark, and the blue
   ordinal ramp for the heatmap. Both were run through
   validate_palette.js against these exact surfaces
   (light #FFFBF5 / dark #1A1917) and pass in both modes.
   Gold and cream are brand decoration only — they never
   encode a value.
