Looking great overall. I left a few non-blocking suggestions to align with established conventions that may have been missed by Cursor and are reinforced by our cursor rules. I also added a few comments around readability and maintainability so this can serve as a stronger long-term pattern example.

Note
Low Risk
Low risk: primarily adds new components/utilities, stories, and tests with minimal impact on existing runtime behavior beyond new exports.
Overview
Adds a new
HeaderRootcomponent to@metamask/design-system-react-nativefor top-level screens, supporting either custom leftchildrenor a title row with optionaltitleAccessory/titleProps, plus an end section viaendAccessoryorendButtonIconProps(icons rendered in reverse order).Includes Storybook stories, a full test suite (rendering/slot precedence, end-section behavior, safe-area top inset, styling), and public exports from the components index. Also introduces and exports a shared
isReactNodeRenderablehelper (with tests) and updatesdesign-system-shareddev deps to includereact/@types/reactfor those tests.Written by Cursor Bugbot for commit 713554e. This will update automatically on new commits. Configure here.
