The Web Content Accessibility Guidelines (WCAG) 2.2 Level AA are the benchmark we are working towards.
We have not yet completed a full independent WCAG evaluation or a published assistive-technology test matrix. We therefore do not currently claim that every Puzzle Workout page conforms to WCAG 2.2 Level AA.
This statement is based on an internal review of the current site, including source-code inspection, keyboard operation, focus behaviour, responsive layouts and reduced-motion support.
