Orchestrated by [pipeline.py](server/pipeline.py) via `ConversationSession`. Supports barge-in (user speaks → cancel in-flight reply). + +2. **Video pipeline** (optional, gated by `config.video.enabled`): per assistant turn, [video.py](server/video.py)'s `VideoEngine` calls [video_models/wan22.py](server/video_models/wan22.py) (LightX2V Wan2.2-I2V) to produce base frames, then [video_models/musetalk.py](server/video_models/musetalk.py) to lip-sync them to the TTS audio, then [video_models/muxer.py](server/video_models/muxer.py) to produce an MP4.
