Component Design Principles\n\n### Component Types\n\n| Type | Use | State |\n|------|-----|-------|\n| **Server** | Data fetching, static | None |\n| **Client** | Interactivity | useState, effects |\n| **Presentational** | UI display | Props only |\n| **Container** | Logic\u002Fstate | Heavy state |\n\n### Design Rules\n\n- One responsibility per component\n- Props down, events up\n- Composition over inheritance\n- Prefer small, focused components\n\n---\n\n## 2. Hook Patterns\n\n### When to Extract Hooks\n\n| Pattern | Extract When |\n|---------|-------------|\n| **useLocalStorage** | Same storage logic needed |\n| **useDebounce** | Multiple debounced values |\n| **useFetch** | Repeated fetch patterns |\n| **useForm** | Complex form state |\n\n### Hook Rules\n\n- Hooks at top level only\n- Same order every render\n- Custom hooks start with \"use\"\n- Clean up effects on unmount\n\n---\n\n## 3. State Management Selection\n\n| Complexity | Solution |\n|------------|----------|\n| Simple | useState, useReducer |\n| Shared local | Context |\n| Server state | React Query, SWR |\n| Complex global | Zustand, Redux Toolkit |\n\n### State Placement\n\n| Scope | Where |\n|-------|-------|\n| Single component | useState |\n| Parent-child | Lift state up |\n| Subtree | Context |\n| App-wide | Global store |\n\n---\n\n## 4. React 19 Patterns\n\n### New Hooks\n\n| Hook | Purpose |\n|------|---------|\n| **useActionState** | Form submission state |\n| **useOptimistic** | Optimistic UI updates |\n| **use** | Read resources in render |\n\n### Compiler Benefits\n\n- Automatic memoization\n- Less manual useMemo\u002FuseCallback\n- Focus on pure components\n\n---\n\n## 5. Composition Patterns\n\n### Compound Components\n\n- Parent provides context\n- Children consume context\n- Flexible slot-based composition\n- Example: Tabs, Accordion, Dropdown\n\n### Render Props vs Hooks\n\n| Use Case | Prefer |\n|----------|--------|\n| Reusable logic | Custom hook |\n| Render flexibility | Render props |\n| Cross-cutting | Higher-order component |\n\n---\n\n## 6. Performance Principles\n\n### When to Optimize\n\n| Signal | Action |\n|--------|--------|\n| Slow renders | Profile first |\n| Large lists | Virtualize |\n| Expensive calc | useMemo |\n| Stable callbacks | useCallback |\n\n### Optimization Order\n\n1. Check if actually slow\n2. Profile with DevTools\n3. Identify bottleneck\n4. Apply targeted fix\n\n---\n\n## 7. Error Handling\n\n### Error Boundary Usage\n\n| Scope | Placement |\n|-------|-----------|\n| App-wide | Root level |\n| Feature | Route\u002Ffeature level |\n| Component | Around risky component |\n\n### Error Recovery\n\n- Show fallback UI\n- Log error\n- Offer retry option\n- Preserve user data\n\n---\n\n## 8.

Testing Principles\n\n| Level | Focus |\n|-------|-------|\n| Unit | Pure functions, hooks |\n| Integration | Component behavior |\n| E2E | User flows |\n\n### Test Priorities\n\n- User-visible behavior\n- Edge cases\n- Error states\n- Accessibility\n\n---\n\n## 10.
