Audit React and Next.js codebases against roughly 50 concrete performance rules spanning re-render hygiene, bundle size, data-fetching waterfalls, images and fonts, list virtualization, and effect discipline, then apply the safest high-impact fixes and prove the win with before/after bundle numbers. Use when someone says "audit React performance", "why is my Next.js app slow", "reduce bundle size", "fix re-renders", "app feels laggy", "optimize my components", "check for waterfalls", "React best practices pass", "lighthouse score is bad", "hydration is slow", or before a launch when a performance sweep of routes and components is needed.
