Accessibility

Supported features

• Keyboard-accessible navigation, filters, dialogs and controls.
• Visible focus states, skip navigation and labelled form controls.
• Responsive layouts without routine horizontal scrolling on phones.
• Colour is not the sole carrier of chart meaning; tables accompany principal analytical views.
• Presentation View enlarges analytical displays for projected teaching.
• Plain, direct UK English and uncluttered content structure.

Known limitations

• Dense analytical tables may still require horizontal movement on small screens.
• SVG chart detail can be demanding in some screen readers; documented tables provide the exact values.
• The interface has been statically and locally tested, but this release has not yet completed independent assistive-technology or real-device conformance testing.

The project aims to improve against WCAG 2.2 AA principles without claiming formal certification at this stage.
