/* ============================================================================
   PREVIOUSLY AUDIO — DESIGN TOKENS · v2.0 — LOCKED SYSTEM (Audio Stage 2,
   2026-10-20). This sheet adopts the locked house system (D-B): navy ink
   #0C121B / charcoal #101623 structure, GOLD #F2BC68 as the signature accent,
   Marathon display + Inter body. The retired Sep-28 "Signal Red" law is
   superseded: red survives ONLY as the verified-live indicator (--pv-live).
   Legacy --pv-red* names are kept as aliases onto the gold family (the
   house migration pattern — same as /css/design-tokens.css legacy aliases)
   so existing components keep working while they migrate stage by stage.
   One source of truth: pages consume these variables, never hardcode values.
   CONVERSION 2026-10-21 (#259 closeout, James's order): surface/ink tokens
   now carry the canonical d3 values NATIVELY in this sheet — the chain no
   longer resolves through the legacy site sheet (--desert-*), and the
   former prefers-color-scheme light block is deleted: this family is
   dark-only, color-scheme comes from design-tokens-d3.css.
