Struct MusicLayerStack 

pub struct MusicLayerStack {
    pub layers: [MusicLayer; 4],
    pub current_vibe: GameVibe,
    pub current_scale: Scale,
    pub beats_per_second: f32,
}

Four cross-fadable music layers driven by the current GameVibe.

• Layer 0 (always): bass drone tuned to floor depth
• Layer 1 (exploration): procedural melody pattern
• Layer 2 (combat): percussion + rhythm pattern
• Layer 3 (boss): full arrangement

Fields

layers: [MusicLayer; 4]

current_vibe: GameVibe
