¿Por qué importa esto?
Images outside the viewport don't need to load immediately. Lazy loading significantly reduces initial load time and improves LCP (Largest Contentful Paint) - a Core Web Vital that Google measures.
¿Cómo se soluciona?
Add loading="lazy" to all <img> tags that are not in the first viewport. Hero images and other above-the-fold images should NOT have loading="lazy" - they should load immediately.
