"""Hello-world FastAPI for SecureAgentRAG HF Space smoke test.

Verifies:
- HF Docker SDK builds a custom image
- Free CPU Basic (2 vCPU / 16 GB) accepts our deps
- Port 7860 reachable from public internet (Egypt origin)

This is a smoke test only. Real backend lands in Phase 2 (see
launch-plan/03-backend-byok.md).
