Notes [#notes]

Accessibility [#accessibility]

termcn exposes the following behavior through Ink's terminal accessibility APIs. This is not a browser ARIA or general WCAG-conformance claim.

* **Keyboard:** Arrow keys move inside the composite; `Home` / `End` select the first or last enabled item; `Enter` / `Space` activate, select, or toggle; `Escape` cancels or closes an owned surface; `Tab` / `Shift+Tab` move between termcn/Ink focus targets.
* **Focus and composition:** Input is active only while the component's focus target is focused, enabled, active, and inside the topmost focus scope.
* **Screen reader:** Ink labels and semantic state expose the component without relying on visual styling alone.
