   Taylor Money — design system
   Dark-first, in the idiom of Rocket Money: near-black plane, raised cards,
   one mint accent, oversized hero numbers, generous rounding.

   Chart colours come from a palette validated for CVD separation and
   contrast against --surface (#15181D). Text colours are held to WCAG 4.5:1
   against the surface they sit on. See server/categories.js for the series
   slots — do not introduce ad-hoc chart hues here.
