    # app gate could never stand in front of it (there is no podman publish to
    # pin, and the manifest declared no port, so the gate neither protected it
    # nor reported it — it served this page to anyone who asked, on LAN,
    # Tailscale and the mesh alike). Binding loopback lets the daemon claim the
    # external addresses and authenticate them; see appgate::listener.
