    # The anouma-runner runs as a Docker container itself (gitea/runner:3),
    # with the host's docker.sock bind-mounted in but no `docker` CLI binary
    # of its own — a job with no `container:` here runs directly inside that
    # minimal runner image and gets "docker: command not found".
    #
    # A plain `docker:27-cli` image (Alpine, no Node.js) doesn't work either:
    # actions/checkout@v4 is a JS action and needs a Node runtime in the job
    # container, which that image doesn't have — it failed at Checkout with
    # exit 127. Using a Node image as the base guarantees Node is already
    # there (same reason the `test` job's node:22-alpine works), and the
    # Docker CLI + ssh client are added via apt. The runner auto-mounts the
    # same host docker.sock into this container (sibling containers — see
    # container.docker_host in the runner's config.yaml), so `docker
    # build`/`push` operate on the host's real Docker daemon.
