Done. Created `/tmp/ws/index.html` with: - **9 pentatonic synth pads** (C minor pentatonic) with hover/active states - **Synth voice** using Tone.js PolySynth with triangle oscillator, filter envelope, and reverb/delay effects - **Play/Stop button** that toggles an arpeggiator sequence - **Tempo slider** (60-240 BPM) to control arpeggiator speed - **Visualizer bars** that animate on each note trigger - **Click-to-start overlay** for browser audio policy compliance - Fully self-contained with no external resources

EVALUATION

4/5 working

Click reveals pentatonic pad grid with play/tempo controls; UI looks clean and functional but keyboard/scroll inputs have no effect.
