/* ==========================================================================
   TerraBright design tokens — SINGLE SOURCE OF TRUTH.

   Carbon g100 (dark, default) / g10 (light, via [data-theme="light"]).
   Typeface: Roboto + Roboto Mono, self-hosted variable woff2.

   index.html mirrors this block inline for first paint — it inlines all of
   its CSS and must not gain a render-blocking request. The mirrored copy is
   fenced between the @generated:tokens sentinels and checked by
   scripts/sync-tokens.py --check, which fails if the two drift apart.

   Every other page links this file directly.
