Pages to scan

Every page in this target carries known accessibility defects, one case per page. This list is the scan surface: 138 pages covering 142 test cases.

It is 138 rather than 142 because 10 cases concern the document itself: its title, its language, whether it has an h1. Those can only happen once per page, so several of them share a page.
