"""ComfyUI container healthcheck: the UI must answer on :8188.

Runs INSIDE the container, where the UI listens (the unit publishes that port on
the host loopback for the homepage status card). ComfyUI only answers once
torch, the custom nodes and the graph are loaded, so a 200 here means the
service is usable rather than merely a live process — the distinction that
matters, because the failure this replaced was a container that stayed "up"
while dying on every start.

HealthCmd in the quadlet splits on spaces into an argv array (podman 5.x v1
generator), which is why this is a file and not an inline `python3 -c`.
