From the WCAG 2.2 AA pass on a fresh Drupal CMS install (axe-core 4.13, 41 anonymous pages).

1.3.1 heading order — on the home page the seven card headings after the H1 were h3. They are level: 2 now, keeping the h5 visual size. axe heading-order was the only finding left on the home page after the theme fixes.

Navigation landmark names — the menu panel and footer copies of the main menu block are labelled "Menu panel navigation" and "Footer navigation" (labels stay hidden). Canvas does not pass an instance label through to the block today, so the theme names them by placement in #3625205; these labels are the right data for when it does.

Closes #3625206.
