Hooks and custom behavior

Add event-driven behavior without changing core files.

Put PHP scripts in includes/hooks/. Lower priority numbers run first.

<?php
add_hook('ClientAreaFooterOutput', 10, function (array $vars): string {
    if (empty($vars['is_logged_in'])) return '';
    return '<div class="text-center small">Need help? Open a ticket.</div>';
});

Core events include client account/login events, client-area output locations, and provisioning events such as PreModuleCreate and AfterModuleCreate. Search the installed source for run_hook( to confirm the exact event and payload.
