// opencode-cloud as a GitHub Codespace — a third home alongside Hugging Face Spaces and
// Railway.
//
// The same Dockerfile serves all three. What differs here is that a dev container starts with
// its entrypoint overridden, so the image's ENTRYPOINT never runs: the server has to be
// started explicitly, and started again after every idle stop.
//
// Codespaces stop after 30 minutes idle by default. That is fine for this use — a stopped
// codespace keeps its disk and restarts under the same name and URL — but it does mean
// postStartCommand, not postCreateCommand, is what boots the server, because only the former
// runs on every resume.
