/* ─── AI Customer-Support Chat Widget (Feature #5 Phase 1) ─────────────
 *
 * Floating bottom-right widget shown on event pages only. Gated server-side
 * by system_settings.chatbot_enabled (event.php).
 *
 * Two states:
 *   - .chat-pill           — collapsed; small "Have questions?" pill
 *   - .chat-panel          — expanded; transcript + input
 *
 * Brand: festivals-v4 uses --primary-red (#dc3545) on a dark background.
 * Keep contrast high — many event pages have busy hero images.
