   MK EMPRESARIAL — diseño del wireframe aprobado.
   El escritorio usa los estilos del propio wireframe (en línea en
   el HTML). Esta hoja aporta lo que el wireframe no define:
   cabecera funcional, submenú, formulario, aviso de privacidad,
   WhatsApp y la versión para celular (pantallas «Mobile»).
