/* ============================================================================
   PREVIOUSLY — DESIGN TOKENS · v1.0 — APPROVED, THE LAW (James, 2026-09-28)
   The law every rebuilt page follows. Derived from the approved song-page
   template ("that's the standard to our pages" — James, 2026-09-28) and his
   standing rules in ~/AGENTS.md.
   One source of truth: pages consume these variables, never hardcode values.
   Platform-agnostic: hex colors, 4pt spacing, dp-convertible radii.
   Web-only notes marked [WEB]. Android maps: px->dp 1:1 at mdpi, blur->elevation.
