   CÓMO EDITAR LOS COLORES (todo está aquí abajo, en :root):
   --navy, --navy-soft, --cream, --cream-2, --gold, --gold-ink, --ink, --muted
   También puedes cambiar textos de sombra, radios y tiempos de animación.
   Estructura del archivo:
     1. Variables y reset
     2. Tipografía y utilidades
     3. Header y navegación
     4. Hero
     5. Planes (imagen ↔ texto alternado)
     6. Cursor personalizado "Ver página" (solo con mouse)
     7. Contacto
