Fires after Formcierge has fully initialised and all internal components are loaded. Use this hook to safely register extensions, custom field types, or third-party integrations that depend on the plugin being ready.

add_action( 'formcierge_init', function () {
    // Plugin is fully loaded — safe to use Formcierge APIs here
    my_addon_bootstrap();
} );

add_action( 'formcierge_init', 'my_custom_addon_init' );

function my_custom_addon_init() {
    // Register custom field types, REST endpoints, etc.
}
