Accessibility

Minimum requirements (v1)

• All interactive controls are reachable via keyboard.
• Visible focus styles.
• No essential information is conveyed by color alone.
• Main flows work without hover (mobile and keyboard users).

Suggested patterns

• Graph nodes: provide a list fallback or “selected node + neighbors” list view.
• Tooltips: do not trap focus.
• Map: provide a textual list of locations for the selected node and neighbors.

Definition of done (a11y)

• [ ] Keyboard-only smoke tour is possible.
• [ ] Selected node has an accessible name and summary.
