The **index.html** file has been created in the current directory. It includes: - A CSS‑styled grid of pentatonic pads that trigger a polyphonic synth with reverb on click. - A play/stop button that runs an arpeggiator sequence using Tone.Transport. - An adjustable tempo slider (60‑180 BPM) that updates the transport BPM in real time. - All required JavaScript is embedded, and the provided `tone.min.js` is loaded via a local `<script src="tone.min.js"></script>` tag. You can open `index.html` in a browser to interact with the pad grid and arpeggiator.
