Title: Add native lazy loading to below-the-fold images Summary - Add loading="lazy" to 243 <img> tags across 58 layout and include files to defer offscreen image requests until the user scrolls near them - Keep above-the-fold images eager (nav logo, homepage hero, blog author headshots) to preserve LCP and avoid layout shift - No JavaScript required — uses the native browser loading attribute, supported by all modern browsers Motivation The site currently loads all images eagerly on every page. Image-heavy pages like the homepage have 40+ images, most below the fold, all fetched on initial load. Lazy loading defers those requests, reducing initial page weight and improving time-to-interactive.

Bearing in mind I see around +/- 5 on the performance scores, depending on how the machine is feeling that day, I reckon this looks promising: Before

The / homepage is where the change looks like it's definitely not just perf noise, and that's the most important one for a first impression. |
