LCP

Covers essential metrics like Core Web Vitals, network timing, and interactivity with clear definitions and measurement contexts, as outlined in the extensive README sections.

Includes ready-to-use JavaScript examples for browser-based measurement, such as calculating DNS latency and TTFB using the Performance API, directly from the network metrics section.

Clearly distinguishes between synthetic testing tools (e.g., Lighthouse) and real user monitoring solutions, helping users choose appropriate data collection methods, as explained in the concepts section.

Aggregates links to official specifications, documentation (like web.dev), and both open-source and commercial tools, saving significant research time for performance professionals.
