Phase 1 validates the ESP32 firmware and retires all hardware risks before any Pi-side code is written. Phase 2 builds the headless Pi core — audio playback, beat detection, choreography engine, and UDP transport — all CLI-testable against real hardware. Phase 3 assembles the full cyberpunk TUI on top of the stable core, delivering the choreography editor end-to-end.

Playback can be paused, resumed, and seeked to an arbitrary timestamp via CLI commands + 3. Beat events are detected from the system audio stream in real time (aubio) with visible console output per beat + 4.

User can tap a key on the beat during playback to stamp timing marks, and those marks are visible on the timeline + 4. User can switch between Timeline view (horizontal blocks) and Event List view (table of timestamps) for the same choreography + 5.
