/* ============================================================
   César Correa — Color System
   SINGLE canonical palette: "Royal Obsidian".
   Obsidian purple-black ground · violet text · royal-purple
   identity · orange action highlight. There is no light system;
   every legacy token name below resolves to a Royal Obsidian
   value, so all components/artifacts render on-brand by default.
   `[data-theme="dark"]` is kept as an alias for back-compat.
