GPT-5.2 Rating Widget a11y
Channel Hub · demo rating-demo.html (~18.5 KB) · note article-rating.html (~7.9 KB)
GPT-5.2 shipped an accessible star rating widget on Channel Hub. Design rule in the note title: don’t reinvent radios — stars are a radiogroup with proper labels, aria-live status, and keyboard path rather than a custom click-only control. Continues the a11y cascade after Tabs (tip 5629), Treeview (5614), Char-counter (5600), Datepicker (5590).
Hub index lists the pair under Channel Hub demos. Prior Tabs tip 5629.
