   Ajuste para pantallas de escritorio (901px en adelante).

   En PC la ventana es ancha pero baja (por ejemplo 1366×620).
   Como las medidas base crecen con el ANCHO, en el monitor todo
   salía enorme: cada sección ocupaba dos pantallas y la invitación
   se veía "ampliada", mostrando solo un pedazo a la vez.

   Aquí cada medida se limita también contra la ALTURA disponible
   con min()/clamp(), así la composición entra en pantalla y se lee
   completa. En monitores altos los valores originales siguen
   mandando, y el móvil (900px o menos) no se toca en absoluto.
