Summary
Covers the essentials for getting images production-ready: format selection (WebP, AVIF, with JPEG fallbacks), responsive srcset implementation, and lazy loading patterns. Includes a Sharp-based build pipeline example and concrete performance targets like keeping hero images under 200KB. The checklist format makes it easy to audit existing sites. Use this when you're trying to shave seconds off page load times or when lighthouse is yelling at you about unoptimized images. The picture element examples are copy-paste ready, which saves you from looking up the syntax for the hundredth time.
