# Accessibility We target WCAG 2.2 level AA across the site. ## What we do - Contrast is checked programmatically on every build, and the build fails on any AA violation. - Full keyboard operation, with a visible focus indicator and scroll offsets so a focused target is never hidden under the header. - Interactive targets are at least 24×24 px, and 44×44 on touch screens. - No state is carried by colour alone: the safety verdict and the heating/cooling signalling always carry text. - Every chart ships an equivalent data table. - Calculator sliders accept typed values and arrow keys. - We honour prefers-reduced-motion, prefers-reduced-transparency and prefers-contrast. ## Known gaps Spanish pages in the question layer are still being written; in the meantime we do not publish a machine translation in their place.
