Iurii Uses: #Core Web Vitals

Our Next.js site was failing Core Web Vitals on mobile and we couldn't figure out why — Lighthouse scores looked fine locally. Iurii's audit pinned it down: an unoptimized hero image on the homepage, third-party scripts blocking the main thread, and a font-loading strategy that was causing layout shift on every page. The fixes were specific enough that one of our developers shipped them over a weekend. CLS dropped from 0.24 to 0.03 and we passed the assessment two crawl cycles later.
