Checks one Browser Quiz (index.html, style.css,
script.js) against the S9 rubric (courses/sdev1003/RUBRICS.md).
It reads the question array out of script.js, then plays the quiz in a hidden
sandboxed frame — clicking the right option each time, and any Next button — with
alert(), prompt(), and confirm() trapped so a dialog
that fires is caught even when the source hides it. Files stay in this browser; nothing is uploaded.
