/* $ICY — Icy Tower pack system design language.
   Ported from the EMRLD (Emerald Arena) design system: deep dark base that
   never flips light, Cinzel display (engraved monument), Outfit body,
   IBM Plex Mono for the 11px letterspaced uppercase "system voice".
   One icy accent (#4DA6FF) + glow (#9FD4FF). GOLD IS RESERVED FOR
   LEGENDARY PULLS ONLY (EMRLD rule: gold = jackpot only). Red for errors
   only. Signature motif: the frost-line — a luminous 1px gradient divider. */
