/* =========================================================
   AI Concierge — site-wide chat widget + Yard Visualizer
   =========================================================
   Uses the site's existing design tokens (see site.css :root) —
   --navy (#000), --blue (#00A7E1), --blue-2, --cream, --paper, --muted —
   so the widget looks native to the rest of avalon-lc.com rather than a
   bolted-on third-party chat plugin.

   Structure:
     .concierge-launcher   — collapsed floating bubble (always present)
     .concierge-panel      — desktop slide-in panel (right side)
     .concierge-panel.is-open      — panel visible state
     On mobile (<768px) the panel becomes a full-screen takeover instead
     of a slide-in, per the approved renderings.
