/* ============================================================
   ZUPI AMBIENT LAYER (prefix: zpa-) — pairs with js/zupi-ambient.js
   Revert: remove this file + js/zupi-ambient.js (+ their 2 tags).
   Features: aurora orbs + film grain, smart glass header,
   magnetic CTAs + double-tick click, WhatsApp-style toasts.
   All motion is transform/opacity only. Full reduced-motion fallback.
