/**
 * ============================================================
 * ALYDRON SECURITY TOOLBOX UI
 * Qué hace: aplicación escalable, responsive y accesible.
 * Por qué existe: reemplaza tabs horizontales por búsqueda, filtros y registry.
 * Riesgos: ninguna regla puede escapar de .alydron-tools-widget.
 * Conexión: estructura de inc/render.php e hidratación de tools/core.js.
