Created a self-contained `index.html` with: - **Visual piano keyboard** (2 octaves, C4–C6) with white/black keys, labels, and active-state highlighting - **ADSR envelope controls** (attack/decay/sustain/release sliders) with real-time visualization - **Waveform selection** (sine/square/sawtooth/triangle) - **Dual input methods**: - Mouse click/drag on keys - Computer keyboard (A–’ keys, including black keys via W/E/T/Y/U/O/P) - **Tone.js integration** for audio synthesis (using the pre-provided `tone.min.js`) Open `index.html` in a browser to use. No network requests or external dependencies.

EVALUATION
Piano UI with ADSR controls; clicking/dragging highlights keys blue, showing visual feedback works as expected.
