A structured mental model for performance work that emphasizes measure-first discipline. You get a clear four-step workflow (baseline, identify, fix, validate), Core Web Vitals targets with actual thresholds, and decision tables for picking the right profiling tool based on symptoms. The bundle analysis and runtime profiling sections are especially practical, showing you what patterns to look for and what actions to take. It includes a Lighthouse audit script you can run immediately. The anti-patterns section is refreshingly honest: profile before guessing, fix the biggest issue first, don't optimize prematurely. Best used when you need to stop guessing and start measuring systematically.
