# Everything runs in Docker (script/docker-*, script/integration-*), so the runner needs
# no JDK, Clojure or Babashka; only a Docker daemon. That means /var/run/docker.sock
# mounted into job containers, or a host-mode runner. Scripts move files with `docker cp`
# rather than bind mounts so they work from inside a job container.
