    # No `init: true` here on purpose. The image makes tini PID 1 itself
    # (Dockerfile ENTRYPOINT), which covers every launch path -- compose, plain
    # `docker run`, the quadlet units and the ECS task definition -- instead of
    # one lever per orchestrator. Setting it here too would nest docker-init
    # around tini and make tini warn that it is not PID 1 on every boot.
    # pids_limit is the backstop: if something ever does leak processes again,
    # this container hits its own ceiling and dies visibly rather than starving
    # the whole host of pids.

    # Includes the shared 30s adapter-settlement window and final cleanup.
