Access
Accessibility
The map must be readable without seeing it, and usable without a mouse.
Text equivalents
Every visualization region has a complete text and list equivalent, available to everyone.
Motion
Reduced-motion preferences are honoured, and no content depends on animation to be understood.
Input
Full keyboard navigation, visible focus states, and touch targets of at least 44px.
Feedback
Accessibility problems are treated as defects, not enhancements.
