Checklist:
1) If pip failed with externally-managed-environment, use:
   python3 -m venv .venv && .venv/bin/python -m pip install -r backend/requirements.txt
2) If browser shows Unauthorized, backend may be running but not initialized/session missing.
3) If frontend opens but no animation, verify OpenClaw events are actually flowing to Star Office backend.
4) In Nomi preview panel, use exact URL of running frontend (usually http://127.0.0.1:19000).
