   Loaded AFTER index.css + theme-pro.css. Uses the same CSS
   variables (--bg, --surface, --accent, --font-head, --font-mono …)
   so it automatically matches the current theme. Does NOT modify
   or override any existing selectors from index.css / theme-pro.css
   (all rules below are scoped under #airc-chat-root).
