"""End-to-end smoke tests against a running server (http://127.0.0.1:8000).

Dataset-independent: assertions verify BEHAVIOR (status codes, envelopes,
shapes, filtering) rather than exact seed counts, so the suite works with
any seed version. Run from the api container or a host with access:

Run:  python tools/smoke_test.py
Env:  SMOKE_USER / SMOKE_PASSWORD (default tester / 123456 — seeded users)
