Measure-don't-guess performance audit across web, mobile, backend, and data layers — produces burndown and optimization plan with no fixes in this pass. No fabricated metrics; every issue needs a measured baseline or [NEEDS PROFILING]. Research-backed proposals for React (code-split, memo, react-window, startTransition), RN (Hermes, JSI, <2s cold start), data N+1/index work with EXPLAIN, and prevention via Lighthouse CI budgets + RUM. Mobile thresholds stricter than web CWV. Use when asked to "performance audit plan", "perf burndown", "measure before optimize", "bundle size audit", "LCP slow", "N+1 audit plan", "plan performance improvements", or "Core Web Vitals audit".
