React Performance Optimization & Bundle Splitting

Optimize rendering using React.memo, useMemo, useCallback, dynamic code splitting with next/dynamic, and production build auditing.

Memoization & Lazy Loading

### React Performance Tools - **`useMemo`**: Caches expensive computation results between re-renders. - **`useCallback`**: Caches function references between re-renders. - **`next/dynamic`**: Lazy-loads non-critical client components dynamically.
