Build a pentatonic synthesizer pad grid and arpeggiator using the provided Tone.js library. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `tone.min.js` (global `Tone`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Show ten labeled pads for two octaves of a C-major pentatonic scale. Clicking a pad plays its note through a synthesized voice with reverb and visibly marks the active pad. - Provide a separate sequence-selection toggle for each pad. Start with a nonempty selection. The arpeggiator repeatedly plays selected notes in ascending pitch order, one note per eighth-note step. - Provide Play, Stop, and a tempo control from 60 to 180 BPM. Tempo and selection changes take effect during playback. An empty selection produces no new notes. - Activate audio through a user gesture. Stop prevents new arpeggiator notes, allowing existing release and reverb tails to decay. Repeated Play must not create overlapping schedulers. - Synthesize every sound; do not load audio files. Verify: Click a pad and check its active feedback. Start the arpeggiator, change one selected note and the tempo, and check that the visible sequence responds. Stop playback and inspect the console for audio-initialization or scheduling errors.

This code creates a pentatonic synthesizer pad grid and arpeggiator using the provided Tone.js library. The pad grid displays ten labeled pads for two octaves of a C-major pentatonic scale. Clicking a pad plays its note through a synthesized voice with reverb and visibly marks the active pad. The arpeggiator repeatedly plays selected notes in ascending pitch order, one note per eighth-note step. The Play, Stop, and tempo control (60 to 180 BPM) are also implemented. The tempo and selection changes take effect during playback. An empty selection produces no new notes. Activating audio through a user gesture is also implemented. Stop prevents new arpeggiator notes, allowing existing release and reverb tails to decay. Repeated Play must not create overlapping schedulers. After opening the index.html file in a browser and completing the user gesture, the following is checked: * Click a pad and verify its active feedback. * Start the arpeggiator, change one selected note and the tempo, and check that the visible sequence responds. * Stop playback and inspect the console for audio-initialization or scheduling errors. To test this behavior, open the `index.html` file in a browser and click on the pads to activate the notes, start the arpeggiator by clicking the "Play" button, change the tempo by adjusting the slider, and stop the arpeggiator by clicking the "Stop" button. The console in the browser developer tools will display any error messages related to audio initialization or scheduling.
