How accessible this service is

We aim to meet WCAG 2.1 level AA: semantic HTML, a skip link, labelled form controls, visible keyboard focus, AA colour contrast, and pages that work when zoomed or on a phone.

Display preferences you can change

The “Aa” button in the header (on every page, including before sign-in) lets you adjust the display:

• Text size — standard, large (112.5%) or extra large (125%); pages reflow without loss of content.
• High contrast — black text on solid white panels, with stronger borders and darker links.
• Colour-blind friendly — status colours switch to the Okabe–Ito palette, and the two trial arms in charts also differ by line pattern (solid vs dashed), so meaning never relies on colour alone.

Preferences are saved on your device only (no account or personal data involved), apply immediately, and persist between visits. Your operating system’s reduced-motion setting is also respected — decorative motion is switched off automatically.
