Accessibility

What's enforced automatically

Every item below is backed by a rule that fails our build or our test suite if it regresses — not just a checklist entry.

• Automated accessibility linting on every code change (missing labels, missing alt text, unlabeled iframes, keyboard-inaccessible click handlers, and more)
• Automated accessibility scans of key pages and components, run on every change
• Skip-to-content links, labeled navigation landmarks, and a visible focus indicator throughout the app
• Support for reduced-motion preferences
• Text and interactive-element colors that meet the 4.5:1 contrast ratio required for WCAG AA

Manually verified

These checks are done by hand and are not (yet) enforced automatically, so treat them as a point-in-time spot-check rather than a standing guarantee.

• Full keyboard navigation through core flows (create, edit, delete)
• Tab order starting from a skip link on every page

Known exceptions

• Uploaded lesson videos do not currently have captions. Embedded YouTube and Vimeo videos are unaffected, since those platforms provide their own caption controls.
