Unit 7. The bay shows the track name (left-click toggles playback, right-click opens the picker — the label stays the control), a play/pause button, the duck badge, and a dB level. No ladder here, deliberately: nothing measures the music bed, and a decorative ladder would break the measured-not-painted rule. A test asserts the bay has no SegmentMeter. The level is real: `ITraxPlayer.UserGain` is a new creator gain multiplied onto the fixed design volume, separate from `LocalGain` (which follows the desktop mute). The VM's `TraxVolumeDb` is the same dB scale as the other faders, so unity means the bed's design level.
