/* ═══════════════════════════════════════════════════════════════
   TITO SILVERSAX — DESIGN SYSTEM
   World: Night Sky / Aurora Star Chart — a deep-space ground with
   prismatic light moving through it: violet, coral, cyan, gold.
   Ties directly to the product itself (The Emotional Star Map maps
   feeling to constellation) rather than being decorative sci-fi.

   Two colors carry real, distinct jobs. Violet is ambient and
   everywhere — eyebrows, card borders, list marks, hover states —
   the color of the sky itself, always present. Coral is rare and
   dramatic: one primary action per view, the one "live" signal, the
   one featured price. Cyan and gold are atmosphere only — aurora
   glows and gradient sweeps on large surfaces — never carrying small
   text, so legibility never depends on them.
