/**
 * Registry for campaign builder element types.
 *
 * Mirrors Fluent Forms' Components.php pattern: a central registry that PHP
 * populates, third-party code can extend via filter, and the JS builder
 * reads via localized data.
 *
 * Usage:
 *   ElementRegistry::get_all()  — returns all registered elements
 *   ElementRegistry::get($type) — returns a single element schema
 *
 * To add custom elements from another plugin:
 *   add_filter( 'better_payment/campaign_elements', function( $elements ) {
 *       $elements['my_element'] = [ 'type' => 'my_element', ... ];
 *       return $elements;
 *   } );
