/* ═══════════════════════════════════════════════════════════════════════════
   GOLDEN GAMES — PREMIUM SKIN (F5)
   One design system for all 24 games: warm ivory game-table on deep navy,
   gold trim, layered depth, and a full motion language (entrance, press,
   success glow, error shake, win celebration). Senior-first: readability,
   large targets, calm motion (no flashing), respects reduced-motion.
