/* ═══════════════════════════════════════════════════════════════════════════
   GENESIS WAVE AI PLAYBOOK — PORTAL DESIGN SYSTEM
   ───────────────────────────────────────────────────────────────────────────
   Token model follows shadcn/ui (https://ui.shadcn.com/docs/theming):
   semantic surface + "-foreground" pairs, a single --radius that drives the
   radius scale, and a --ring token for focus. Values are the Genesis Wave
   BRAND_CONTEXT.yaml v2 palette. See DESIGN.md for the token map and the
   component recipes (button / card / badge) that mirror shadcn's variants.

   The site has no build step, so the tokens are consumed as plain CSS custom
   properties instead of Tailwind utilities. If the portal ever moves to a
   React/Next stack, the :root block below drops straight into shadcn's
   globals.css unchanged.
