Clarification on middleware

// middleware/auth.ts
import { useSession } from "~/lib/auth-client";

// Protects routes - redirects unauthenticated users to sign-in
export default defineNuxtRouteMiddleware(async (to) => {
  const session = await useSession();

  // If not logged in, redirect to sign-in page
  if (!session.value) {
    return navigateTo("/auth/sign-in");
  }
});

<script>
  definePageMeta({
  middleware: ['auth'] // Protects entire /dashboard section
});
</script>
