   chat.css — OpenTalk random chat
   - Light/dark via CSS vars (theme switch is instant)
   - Top bar carries brand (left) + online count + theme toggle (right)
   - Bottom bar is slim (mode pill) only on the chat page
   - Video tiles have a FIXED aspect ratio + max size — they DO NOT
     stretch to the user's webcam resolution
   - Mobile-first responsive
