The **index.html** file has been created, loading the provided **tone.min.js** and implementing a playable piano keyboard: - White and black keys are rendered with CSS. - Mouse clicks and computer keyboard keys trigger notes. - Uses a **Tone.PolySynth** with an ADSR envelope for sound synthesis. - Visual feedback highlights pressed keys. You can open `index.html` in a browser (offline) and play the piano.
