/**
|

|
* [Gitea #342] Whether a voice channel with an `io.lotus.voice_limit` is full.
|
||
|
|
* Counts distinct PEOPLE, not call memberships: a MatrixRTC membership is per
|
||
|
|
* device, so one user on desktop + phone (or with a crashed tab's membership
|
||
|
|
* not yet expired) used to fill two slots. This matches the server-side guard
|
||
|
|
* (matrix `voice-limit-guard.py`, which reduces LiveKit identities to users).
