/* shard room-annabel (annabel.css) — the ANNABEL THEME for Word Lab (the English tutor).
   Gaming-noir deep palette + teal accents + Space Grotesk display stack. Sets the
   --wl-* token VALUES the shared engine consumes (token NAMES are declared by the
   engine's 00-base.css); adds Annabel-only chrome + the earned-answer RANK-UP flourish.
   Loaded AFTER engine.css so these values win. Owns ONLY .wl-room-annabel-* + the
   --wl-* token values — never the engine's .wl-app/.wl-stage/.wl-nav component rules.
   No assets, no webfont files: "Space Grotesk" is named and falls back to system. */
