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:** `Enter` / `Space` activate the focused action when enabled; `Escape` dismisses or cancels when supported; `Tab` / `Shift+Tab` move through 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:** Screen-reader mode removes decorative output while preserving meaningful labels and state.
