Quick way to find the offender
From frontend/ run:
rg -n "chatroom" app/globals.css app
If it shows something like @import "./chatroom";, that’s the culprit.

Recommended structure (avoid this class of issue)
If you want shared/global styles, keep them outside route folders, e.g.:

1. frontend/styles/globals.css
2. import it only in app/layout.tsx
   import "../styles/globals.css";
