 * Estilos de la landing BIOW (Beauty By Issie) para un tema hijo de GeneratePress.
 *
 * IMPORTANTE: este archivo se encola SOLO en la plantilla "BIOW Landing"
 * (ver snippet wp_enqueue_scripts en functions.php) y DESPUES del CSS de
 * GeneratePress, de modo que sus reglas sobrescriben las del tema padre.
 *
 * NO pegues este contenido en el style.css global del tema hijo: el reset
 * `* { margin:0; padding:0 }` de abajo rompe el resto del sitio si se carga
 * en todas las páginas. Debe quedar aislado a la landing.
 * -----------------------------------------------------------------------------

/* === Neutralizar GeneratePress en la página de la landing ================== *
 * La plantilla es de lienzo completo (sin .site / #page), así que casi nada
 * del tema padre aplica. Estas reglas son por seguridad: si GeneratePress
 * inyecta contenedor, ancho o espaciados, los anulamos para que la landing
 * controle el layout por completo.                                            */
