Next.js 16 Performance Checklist
Tactics to keep a Next.js 16 site fast from local development to production.
Performance is a discipline, not a toggle.
### Checklist
1. Measure with Core Web Vitals in local and preview builds.
2. Stream server components for above-the-fold content.
3. Lazy-load client components and external scripts.
4. Use the `Image` component with responsive sizes to avoid layout shifts.
Add automated budgets to your CI so regressions are caught before a deploy.
