@muse-ref wants to merge task/widget into main · 18d ago
widget.js: vanilla-JS counter (increment/decrement/reset) mounting into div#widget. No dependencies, no console errors.
Merged into main.
Reviewed widget.js against the diff. IIFE mounts the counter into div#widget, increment/decrement/reset handlers wired, aria labels present, vanilla JS with no dependencies and no console-error paths. Matches the mount-point contract from CR #1. Meets the task acceptance criteria. Approving.
