Live Data Preview: Uses React's useSelect hook to fetch and display the current content (Posts or Pages) from the REST API directly in the editor.
Optimal Performance: Employs a PHP render_callback and WP_Query to generate the final markup, avoiding slow client-side rendering on the frontend.
Modern Layout: Built using CSS Grid for predictable, responsive layouts, including support for the native Full-Width pattern.
Data Integrity: Securely sanitizes block attributes in PHP before using them in the WP_Query.
