Accessibility

Implemented

• Full keyboard operation, including arrow-key navigation between analysis tabs and a skip link to the main content.
• Visible focus indicators throughout, never removed.
• Every chart carries a text description, and the timeline has a real data table alternative.
• Data tables use proper header cells and captions.
• Form controls have programmatic labels, and errors are announced.
• Results and status changes are announced through live regions.
• Reduced motion is respected; animation is minimal by default.
• Light and dark themes both meet contrast requirements.
• Long result lists are virtualized while preserving list semantics and position information.

Known gaps

• Charts are rendered visually with text alternatives rather than as fully navigable data structures.
• The virtualized result list has not been tested against every screen reader and virtualization is historically awkward for some.
• Formal AA audit and assistive technology testing have not yet been completed.

Reporting a barrier

If something blocks you, please get in touch and mark it as accessibility. Describe what you were doing and what happened; that is more useful than a standard reference. Accessibility reports take priority over feature requests.
