The playable piano keyboard is ready! **Open `/tmp/ws/index.html` in a browser** to use it. Features: - **Mouse & Keyboard Control**: Click keys or use `A` `W` `S` `E` `D` `F` `T` `G` `Y` `H` `U` `J`. - **ADSR Envelope**: Smooth attack, decay, sustain, and release for realistic notes. - **Visual Feedback**: Keys light up when played. - **Self-Contained**: No external resources—just open the file.
