      # Watchtower v1.7.1's bundled docker client defaults to API 1.25 and
      # its version negotiation fails against Engine 29 (min API 1.40),
      # leaving the container in a crash loop. Pinning the API version is
      # the documented workaround. 1.44 is safely inside the supported
      # window on this host (server 1.55, min 1.40).
