/* =========================================================================
   ESTILO INSPIRADO EN SITIOS EDITORIALES DE TURISMO/NATURALEZA
   (hero cinematográfico, navegación transparente, tipografía serif + sans,
   fotografía a pantalla completa, mucho espacio en blanco)

   IMPORTANTE SOBRE LAS IMÁGENES:
   Como este proyecto no incluye fotos reales, todas las "fotos" del diseño
   (hero, tarjetas destacadas, servicios, sección "Nosotros") están hechas
   con degradados de CSS que imitan tonos de fotografía de naturaleza.
   Búscalas en la sección 3 (".photo-1" a ".photo-6") y reemplaza el
   "background" por algo como:

     background-image: url('../images/tu-foto.jpg');
     background-size: cover;
     background-position: center;
