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:** `Left` / `Right` move by grapheme, `Home` / `End` move to the boundaries, and `Backspace` / `Delete` remove one complete grapheme. `Enter` submits or confirms (`Ctrl+Enter` in TextArea); `Tab` / `Shift+Tab` leave through Ink focus traversal.
* **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.
