The minimum WCAG-aligned accommodations every site owes the humans who land on it — readable contrast, alt text, navigable structure.

Why each item matters
- Image alt text coverage · methodology →
Screen-reader users can't navigate a site whose meaningful images have no alt text. Bar passes on ≥80% coverage.
- Sufficient color contrast · methodology →
Body text below WCAG AA contrast is unreadable to a meaningful slice of visitors. Bar passes on no critical violations.
- Valid heading hierarchy · methodology →
Headings are how assistive tech navigates the page. A page with no H1 or with H1→H4→H2 leapfrog isn't navigable.
