  • SequencerScene: full-screen piano roll UI with 25-note grid (C3–C5)
    and 16-step sequencer, optimized for mobile portrait
  • Web Audio API synth using sine+harmonic oscillators for marimba timbre
  • Lookahead scheduler (100ms) with setInterval tick for accurate timing
  • BPM slider (40–200), play/stop toggle, clear button, step cursor
  • turbopack.root fix to resolve pre-existing build error
