 * Query arguments to fetch posts while filtering based on the custom ACF field 'post_visibility'.
 *
 * Filtering logic:
 * 1. Posts where 'post_visibility' **does not exist** (i.e., no visibility option selected) are included.
 *    - This ensures that posts without a manually set visibility option are shown.
 *    - The default option when 'post_visibility' is not explicitly selected is "website"
 * 2. Posts where 'post_visibility' is explicitly set to 'lva-platform' are excluded.
 * 3. Posts with any other value ("website" or "everywhere") are included.
 *
 * The 'relation' => 'OR' ensures that either of these conditions can be true:
 * - If the field does not exist → Show the post.
 * - If the field exists and IS NOT set to 'lva-platform' → Show the post.
 * - If the field exists and is set to 'lva-platform' → Exclude the post.
