/* ════════════════════════════════════════════════════════════════════════
   HEFYR design system v3 — "QUIET AUTHORITY"
   The true brand: forge, kiln, heat, earth. Two first-class themes —
   dark ("night in the forge", default identity) and daylight (the deck on
   paper). Rust is scarce. Numbers are mono. Confidence colors are data-only.
   Nothing moves, exists, or speaks without earning it.
   Every color on this site lives between TOKENS-BEGIN and TOKENS-END —
   the color auditor (_harness/audit-color.cjs) fails the build otherwise.
