|
|
|
## Risk Mitigation
|
|
|
|
| Risk | Mitigation |
|
|
|------|-----------|
|
|
| Bundle size exceeds target | Tree-shaking, code splitting, lazy loading |
|
|
| Search index too large for client | Pagination, server-side fallback, index pruning |
|
|
| Design system inconsistent | CSS custom properties, component tests, design tokens |
|
|
| Mobile layout issues | Test on real devices, container queries, touch targets |
|
|
