-The Testing Library already provides methods for querying DOM elements.
+Disallow direct access or manipulation of DOM nodes in favor of Testing Library's user-centric APIs.
 
 ## 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.
