/*
 * RAG floating chat widget.
 *
 * Brand-neutral defaults — picks up the host page's --bs-primary
 * when available (Bootstrap 5 sites) but works on any CSS context.
 * Overrideable via CSS custom properties scoped to .ws-meilisearch-chat-bubble
 * or .ws-meilisearch-chat-panel without touching the markup.
 *
 * Mobile (< 480px wide) → panel becomes full-screen sheet.
 * Desktop → 380×580 corner panel anchored above the bubble.
