 * Ruta: frontend/assets/css/theme.css
 * Descripción: Base visual pública RET Foundation.
 * Cambio aplicado: se eliminaron reglas globales invasivas que afectaban header/topbar,
 * footer, botones nativos y hero. El topbar externo queda controlado por
 * frontend/includes/_topbar_ext.php y el footer por frontend/includes/_footer_ext.php.
