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.
