"""Single-client smoke test against a running red-button Docker container.

Run after::

    docker run -d --name red-button-test -p 8000:8000 red-button:latest

Then::

    python scripts/smoke_test_docker.py

Validates PROJECT.md Section 24.1 pre-flight items 2-3 (image runs, server
accepts client connections). The OpenEnv ``EnvClient`` is async by default;
we use the ``.sync()`` wrapper so this script reads top-to-bottom without
``await``-noise.
