   Shriram Hospital Chatbot — chatbot.css
   LOCATION: public/css/chatbot.css

   RULES:
   - No :root or body styles — only chatbot elements
   - All CSS variables defined on #sr-chat-toggle and #sr-chatbox
   - Mobile: true fullscreen, background completely hidden
   - Desktop: chatbot never gets cut from top

   FIX v3:
   - Desktop: top+bottom dono set — top-cut band
   - Mobile: keyboard ke peeche input field jaane ki problem FIXED
     Solution: 100dvh (dynamic viewport) + visualViewport JS API
