   Design tokens

   Brand hexes (from assets/Pinwheel Brand Guidelines.pdf) are used as-is
   for UI chrome (buttons, links, badges backgrounds, logo). For data-viz
   marks (bars, status dots) the brand's teal/orange/pink are too light to
   read reliably against a surface or pass CVD-separation checks, so
   --status-* below are darker, more saturated steps of the same three
   hues -- validated with the dataviz skill's palette checker in both
   light and dark mode. See MEMORY / build notes for the derivation.
