could hang is bounded by `anyio.fail_after(5)`. A test that must let in-flight deliveries
settle before teardown (an abandoned request's late error response, say) may use
`anyio.wait_all_tasks_blocked()`: the whole suite is single-loop and task-driven, so
quiescence is deterministic. The HTTP and OAuth tests drive the Starlette

delivers each response chunk as the server produces it — full duplex, but still no sockets,
threads, or subprocesses anywhere outside the one stdio test.
