+## Defer Non-Critical Third-Party Libraries
+
+Analytics, logging, and error tracking don't block user interaction. Load them after hydration.
+
+**Incorrect (blocks initial bundle):**
+
+```tsx
+import { Analytics } from "@vercel/analytics/react";
+
+export default function RootLayout({ children }) {
+  return (
+    <html>
+      <body>
+        {children}
+        <Analytics />
+      </body>
+    </html>
+  );
+}
+```
+
+**Correct (loads after hydration):**
+
+```tsx
+import dynamic from "next/dynamic";
+
+const Analytics = dynamic(() => import("@vercel/analytics/react").then((m) => m.Analytics), {
+  ssr: false,
+});
+
+export default function RootLayout({ children }) {
+  return (
+    <html>
+      <body>
+        {children}
+        <Analytics />
+      </body>
+    </html>
+  );
+}
+```
