+The persistent Meet voice comes from
+`messages.tts.providers.elevenlabs.voiceId`. Agent replies can also use
+per-reply `[[tts:voiceId=... model=eleven_v3]]` directives when TTS model
+overrides are enabled, but config is the deterministic default for meetings.
+On join, the logs should show `transcriptionProvider=elevenlabs` and each
+spoken reply should log `provider=elevenlabs model=eleven_v3 voice=<voiceId>`.
