/*
 * "Ask JW Cruises": the visitors' chat bubble and panel (plan step A18, proposed; assets/js/visitor-chat.js builds them).
 * Colours are main.css's variables, so Daniel's colour changer and the dark sections move them too. Text is large enough
 * to read without zooming (1rem and up). Every animation and transition sits inside
 * @media (prefers-reduced-motion: no-preference) (Daniel, 2026-10-05): a device set to reduce motion gets none.
 * The bubble sits bottom right; the back-to-top button is bottom left (main.css .scroll-top), so they never meet.
