"""frank-medium container healthcheck: the port's /health must answer 200.

Runs INSIDE the container. The vLLM /health endpoint only answers once the
engine is up (weights loaded, cudagraphs captured), so a healthy container is
a serving container, not merely a live process. PORT selects the endpoint so
the probe follows the unit's Environment=PORT rather than hard-coding the
fleet port. The HealthCmd in the quadlet splits on spaces into an argv array
(podman 5.x v1 generator), which is why this lives in a file rather than an
inline python one-liner.
