 ## Rule Details
 
-This rule aims to disallow direct access and manipulation of DOM nodes using native HTML properties and methods — including traversal (e.g. `closest`, `lastChild`) as well as direct actions (e.g. `click()`, `focus()`). Use Testing Library’s queries and userEvent APIs instead.

+
+> [!NOTE]
+> This rule does not report usage of `focus()`, because imperative focus (e.g. `getByText('focus me').focus()`) is recommended over `fireEvent.focus()`.
+> If an element is not focusable, related assertions will fail, leading to more robust tests. See [Testing Library Events Guide](https://testing-library.com/docs/guide-events/) for more details.
