   PearlFibers.com — design tokens
   The single source of truth for color, space, type, radius, motion.
   Components reference tokens ONLY — a raw color in any other stylesheet is
   a build failure (IMPLEMENTATION-PLAN §3).

   Accent is the brand blue #5093c9 (owner ruling 2026-07-20, supersedes the
   pearl-green derivation). The interactive accent is tuned per theme so every
   pairing below holds WCAG AA (validated 2026-07-20 with the qa contrast
   script):
     light: white on --blue 5.45 · --accent-strong link on --bg 6.03
