   TÉCNICA: pseudo-elemento ::before de sections-wrapper

   de apilamiento del wrapper (z-index:1 en root).

   Por qué funciona:
   - z-index:-1 dentro del wrapper queda detrás de los
     bloques pero dentro del mismo contexto → las secciones
     semi-transparentes SE MEZCLAN con este fondo, no con body.
   - position:fixed hace que permanezca estático mientras
     el contenido hace scroll-snap → efecto de profundidad.
