voice-limit-guard (:8070) is meant to be the only way to get a LiveKit
token, but lk-jwt-service bound :8071 on every interface, so any LAN
host could mint an unguarded token (no max_users, full publish sources
in audio-only rooms). The guard runs on the same LXC: document the
loopback bind in the setup steps and the port table.
