How do you explain and optimize Core Web Vitals metrics, specifically CLS, LCP, and INP?
Explain what each metric measures, how its browser-observed value is produced, and how you would diagnose and improve a page that performs poorly. Include the difference between field data from CrUX or real-user monitoring and lab data from Lighthouse or PageSpeed Insights. Keep the answer focused on modern web browsers and production web performance.
