### Musical Intelligence
- Beat-quantized: All actions on downbeats (|ψ| ≤ 15°)
- Key-aware: Compatible harmonic transitions
- Energy-matched: Sound follows movement intensity
- Phrase-sensitive: Respects musical structure
- Safety-first: Never breaks the flow

🎬 Demo Scenario

[Setup]
- Serato running with Track A loaded
- SuperCollider mastering chain active
- Studio engine running with DJ agent (ghost mode)
- Motion sensors streaming

[00:00] Start moving to rhythm
        Console: 👻 [GHOST] Would execute: PLAY_A at |ψ|=2°

[00:05] High-energy gesture
        Console: 👻 [GHOST] Would execute: LOOP_4_A at |ψ|=8°

[00:10] Switch to assist mode
        You: dj_agent['planner'].set_mode('assist')

[00:15] Big gesture (high energy)
        Console: ✅ [ASSIST] Executing: LOOP_4_A
        Serato: Deck A now looping (4 beats)
        Audio: Filter opens, reverb increases

[00:30] Rhythmic hands
        Console: ✅ [ASSIST] Executing: ECHO_TAP_A
        Audio: Echo taps in sync with movement

[01:00] Switch to auto mode
        Console: 🤖 [AUTO] Executing: FX_TOGGLE_1_A
        Serato: Reverb toggles automatically

[End] Full motion-driven performance achieved!
