Core Web Vitals
Google performance metrics that feed directly into search rankings: LCP, INP, CLS.
LCP (Largest Contentful Paint) measures how fast the main view appears, target < 2.5s. INP (Interaction to Next Paint) measures responsiveness, target < 200ms. CLS (Cumulative Layout Shift) measures visual stability, target < 0.1. Our themes are tuned to meet all three by default.
