The server sends the bandwidth policy because the same rule is enforced in
video authorization. The hook only mirrors that policy so the UI avoids
requesting live video when snapshots are the intended non-turn experience.
The server evaluates the global controllable-user threshold because that
same decision is enforced in socket video tokens and MediaMTX auth. This
hook only mirrors the active result so the browser does not request live
video when snapshots are already the authoritative non-turn outcome.
