It starts from Lighthouse performance audits to find what is slowing things down.
In practice it spots bottlenecks in code and assets and prioritizes them by their impact on Core Web Vitals.
It also suggests concrete optimizations with code examples and helps measure the gain with before-and-after metrics.
