Arpeggiator pad · gpt-5.6-luna-pro
Using the pre-provided tone.min.js (global Tone), build a clickable pentatonic pad grid that triggers a synth voice with reverb, plus a play/stop button that runs an arpeggiator sequence at an adjustable tempo. All sound synthesized, no audio files.

**Looking into modifications** I’m thinking about needing to modify the index.html file in the /tmp/ws directory. I realize I’ll have to inspect the files there to see what needs changing. It sounds simple enough, but I want to ensure I'm thorough in my approach. I'll carefully check the contents to understand what modifications are necessary before diving in. Let’s make sure everything is on track!

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
