"""End-to-end API smoke test against a running ImmunoOrg server.

This test is intentionally written so it skips silently when no server
is reachable on ``localhost:7860`` — that way ``pytest tests`` still
passes in CI / local dev where you haven't booted ``uvicorn server.main:app``
yourself. To actually exercise it, run::

    uvicorn server.main:app --port 7860 &
    pytest tests/test_api.py -v
