Done.
Created `/workspace/index.html` — a fully self-contained 16-step drum machine: - **Grid**: 4 tracks (Kick, Snare, Hi-Hat, Clap) × 16 steps, click to toggle, with a beat-grouped layout and moving playhead highlight. - **Synthesized sounds** (pure Web Audio, no samples): - Kick: pitch-dropping sine + noise click transient - Snare: triangle body + band-passed noise - Hi-hat: high-passed noise with fast decay - Clap: band-passed noise with a multi-burst envelope - **Transport**: Play/Stop with a 25 ms lookahead scheduler for sample-accurate timing, BPM slider (60–200) applied live, and a Clear button. - Pre-loaded with a basic house pattern; clicking a cell auditions the sound instantly. Just open the file in a browser — no network or external assets needed.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
