/* ============================================
   AI ASSISTANT CHAT BUBBLE STYLES

   The AI chat offcanvas uses the shared .msg-* template
   (see style.css "MESSAGE BUBBLE TEMPLATE" section) so it
   feels like a cousin of the Driver Messages and User Chat
   offcanvases. The styles below are limited to:
   - the floating edge-tab toggle button
   - the offcanvas shell + gradient header (the "this is AI"
     signal so users don't confuse it with a human chat)
   - a third .msg-bubble--ai variant + bot avatar
   - the typing indicator dots
   ============================================ */

/* Floating toggle button removed. .ai-chat-toggle was a 14px edge tab
   pinned to right:0, so it sat on top of .main's scrollbar on every page.
   The offcanvas is opened from the header Help menu (#helpMenu) and from the
   Ask row in quick search, both targeting #aiChatOffcanvas. */

/* Offcanvas shell — wider than the driver messages offcanvas (420px) because
   AI replies often include markdown tables / lists that need horizontal room. */
