Accessibility statement

What is in place

• Semantic structure: one heading per page level, landmarks, a skip link, breadcrumbs
• Keyboard access to every control, including the interactive 3D model (arrows rotate, + / − zoom, 1–4 focus a stage, 0 resets, Esc clears); visible focus indicators
• Text alternatives for images and a written description of the system diagram; labels on the 3D model are real buttons
• Colour contrast of at least 4.5:1 for text; information is never conveyed by colour alone
• Forms with visible labels, instructions, error messages tied to fields, and a status message announced to assistive technology
• Reduced-motion preferences respected: no auto-rotation or flow animation when your system asks for less motion
• Content reflows to a 320 px viewport without horizontal scrolling; wide tables and diagrams scroll inside their own container

Known limitations

• The 3D model requires WebGL; where it is unavailable, the static diagram and its text description are shown instead.
• PDF documents published before 2026 (press releases, policies, the 2022 presentation) were not produced to accessibility standards. Ask us for the information in another format.
• Testing so far has used automated checks and manual keyboard review in Chromium-based browsers. Screen-reader testing on other browsers is planned before public launch.
