     - background-position: Controla dónde se centra la imagen
       Formato: horizontal% vertical%
       Ejemplos: "35% 25%" = 35% desde la izquierda, 25% desde arriba
                "center center" = centrado
                "right 30%" = derecha, 30% desde arriba

     - background-size: Controla el tamaño/escala de la imagen
       Opciones: "cover" (llena el espacio, puede recortar)
                "contain" (imagen completa visible, puede dejar espacios)
                "120%" (escala personalizada, números mayores = más zoom)
