# Frontend Performance Accessibility

> Hold a React frontend to its Lighthouse performance budgets (desktop 95 / mobile 85, integer-percent floors mapped by quality.lighthousedesktop and quality.lighthousemobile), keep web-vitals, bundle size, and code-splitting healthy, defend deferred-DI render paths, and meet WCAG 2.2 AA accessibility — pairing with the accessibility-audit skill and the accessibility-lead agent team. Use when improving frontend performance, Lighthouse scores, web-vitals, bundle or code-split cost, render-path / deferred-DI work, or accessibility.
