/* ===== Móvil: Entrada y Salida como páginas deslizables =====================
   El corte de 700px de todas las media queries móviles es MOBILE_MAX_WIDTH
   (mobile-pager.js); CSS no puede leerlo, así que si cambia allí, aquí también.
   Bajo 700px las columnas no se apilan: van una al lado de la otra en un
   carrusel con scroll-snap nativo (el swipe lo resuelve el navegador) y cada
   una desplaza su contenido en vertical por separado. Así la página corta no
   hereda la altura de la larga y cada una conserva su posición al volver.
   El margen lateral pasa del body a cada bloque (--gutter) para que el
   carrusel ocupe todo el ancho y no recorte las páginas a 2rem del borde. */
