/* NOTA: aquí vivía un override con `display: flex !important` para
   ≤900px que anulaba la regla de design-system.css. Su especificidad
   (0,3,1) le ganaba a `.nav-link { display:none !important }` de más
   abajo, así que en móvil se veían "Nosotros · Industrias · Contacto"
   AL MISMO TIEMPO que el hamburguesa, y el CTA quedaba escondido.
   Se eliminó: ahora el breakpoint es uno solo, 900px. */
