/* The Premium Nexus assistant: WhatsApp launcher + the AI chat assistant (js/concierge.js).
   Concept G "Portoro": a stone sheet with an 18px radius (the one rounded exception, DESIGN.md),
   a gold-tinted hairline, a Gloock title, gold visitor bubbles with black ink, 2px inputs and
   pill suggestions. Below 480px the sheet becomes a full-screen view that respects safe areas.
   Motion is transform and opacity only, and switches off with reduced motion. */
