/* Permit AI — self-hosted chat widget, gated by /api/ai-chat/status. See js/permit-ai-widget.js.
   Bottom-right, the conventional chat-widget corner. --pai-offset is kept in sync with the cookie
   consent banner's live height by permit-ai-widget.js so the two never overlap while the banner
   (shown on first visit only) is up — once it's dismissed the offset drops back to 1rem, clear of
   the cookie-settings icon which lives in the opposite (bottom-left) corner. */
