Fix these first

Required findings only: legally required first (UK accessibility regulations (PSBAR 2018): WCAG 2.1 AA), then the rest of the WCAG 2.2 AA target. Within each, ranked by pages affected × severity × people reached. Fixing a shared component often clears many pages at once. Issue links go to the full bug detail on the Accessibility page.
