/* ==========================================================================
   ESCALA GENERAL DEL SITIO EN PANTALLAS GRANDES (125%, TODAS LAS SECCIONES)
   --------------------------------------------------------------------------
   En monitores grandes el contenido queda limitado a 1260px, por lo que la
   página se veía pequeña y "alejada". Desde 1600px de ancho se aplica el
   mismo efecto que el zoom del navegador al 125%: todo (texto, imágenes,
   tarjetas, menú y pie de página) crece un 25% de forma proporcional.

   Por debajo de 1600px no se aplica nada: ahí el contenido ya ocupa todo el
   ancho disponible y el diseño se ve como siempre.

   Para cambiar la escala solo hay que modificar --escala-sitio: las
   compensaciones de abajo se recalculan solas.

       El zoom multiplica los valores expresados en vh y vw, así que las
       ventanas de imagen, las portadas a pantalla completa y las secciones
       alineadas con 100vw podrían desbordarse. Estas reglas solo se activan
       cuando el navegador realmente las multiplica: lo detecta
       js/header-footer.js y agrega las clases "zoom-escala-vh" / "-vw".
       En los navegadores que ya respetan estas unidades, todo queda igual.
