Accessibility statement

This platform is designed to be fully accessible. Every text colour pair achieves a contrast ratio of at least 4.5:1 and every non-text boundary at least 3:1. All interactive elements have visible focus indicators. All forms have associated labels and error announcements.

The claim is machine-checked on every commit rather than asserted. Continuous integration runs a contrast gate over every colour pair in the theme and a colour-vision-deficiency gate that repeats those measurements under simulated protanopia, deuteranopia and tritanopia. The build fails if any of them regress.

No information is conveyed by colour alone. Status labels carry an icon and a word as well as a tint; error messages carry a warning icon and the word “Error”; added and removed lines in a comparison carry + and − markers. Any two colours that mean different things and are hard to tell apart under any simulated colour-vision deficiency must declare the non-colour cue that separates them, and the build fails if one does not.

Nothing on this platform flashes, blinks or pulses. The only continuously moving element on the public site is the acknowledgements ticker on the landing page: it travels slowly and in a straight line. Visitors who set the system prefers-reduced-motion: reduce preference see it static, with the names still available in a scrollable list. The global stylesheet also suppresses animation for those visitors on every route as a second line of defence.

All interactive elements are operable by keyboard. A skip-to-content link is available at the top of every page. Modal dialogs trap focus and can be dismissed with the Escape key.
