The UI intentionally hides these settings, but the backend still supports them through `POST /api/session`.
- Frame rate defaults to `24fps`. Lower it if the client cannot keep up.
- Max width defaults to `960px`. Lower it first if bandwidth or image decode is the bottleneck.
- JPEG quality uses ffmpeg's `-q:v` scale, where lower is better. Set the default with `JPEG_QUALITY`; `7` is the fallback, `2` is high quality, and `18` is rough but lighter.
- Max width defaults to `960px`, and the client now caps each session to its viewport width. Lower `DEFAULT_FRAME_WIDTH` first if bandwidth or image decode is the bottleneck.
- JPEG quality uses ffmpeg's `-q:v` scale, where lower is better/larger. Set the default with `JPEG_QUALITY`; `7` is the fallback, `2` is high quality, and `18` is rough but much lighter.
- Audio defaults to stereo MP3 at `160k`. Tune with `DEFAULT_AUDIO_BITRATE`, `DEFAULT_AUDIO_CHANNELS`, and `DEFAULT_AUDIO_SAMPLE_RATE`.
