| * Fix WordPress 6.9+ CSS Loading Issue | |
| * | |
| * WordPress 6.9 introduced an optimization that only loads CSS for blocks | |
| * actually used on a page. This breaks styling for: | |
| * - Classic Editor content (no block markup) | |
| * - ACF fields (dynamically rendered) | |
| * - Shortcodes like WPForms (not recognized as blocks) | |
| * | |
| * This filter disables the optimization, restoring pre-6.9 behavior where | |
| * all CSS loads unconditionally. | |
| * | |
| * @since 1.0.0 | |
| * @see https://core.trac.wordpress.org/ticket/64099 | |
