Prioritised recommendations (click to expand)

P1Cut the mobile JavaScript bundle
Mobile TBT is 3959ms from 1.2 MB of JavaScript. Defer and code-split non-critical JS, remove unused libraries, audit third-party scripts.
P2Improve mobile LCP
Mobile LCP is 6.3s. Preload the hero image, reduce server response time and remove render-blocking CSS/JS.
P2Compress oversized images
Desktop loads 29 MB, almost all images. Serve WebP/AVIF, size responsive images and lazy-load. Aim under 2 MB.
