// MixerScenePanel — Scene management for the digital mixer.
|
||||
//
|
||||
// Displays 8 numbered scene slots (like a hardware digital mixer).
|
||||
// Each slot can store/recall a full mixer state snapshot.
|
||||
// Uses backend mixerSaveScene / mixerLoadScene / mixerGetScenes WebSocket messages.
|
||||
//
|
||||
// The panel can be embedded in the PerformanceView or used standalone.
