"""Production smoke tests — must pass after every merge to main.

Run after deploy completes (~2-3min after merge). CI workflow:
  cd backend && uv run pytest tests/smoke/test_prod_smoke.py -m prod_smoke -v

Each test makes a real HTTP call to https://gendsgn.ru, validates response
structure (not exact data) и crash regressions, and reports timing.

Marks:
- @pytest.mark.prod_smoke — skip by default in CI, run only on-demand
- @pytest.mark.slow — long-running (≥5s)

Tests cover the regression surface that bot review window cannot catch:
- Schema migrations break field types → AttributeError на user actions
- Frontend bundle ↔ backend contract drift
- Auth/admin endpoints за токеном
- Background workers + Celery queue
