  title: 'Create Next App',  // Default!
  description: 'Generated by create next app',  // Default!
};

// No custom favicon — still using Next.js default
// No custom 404 page
// No robots.txt or sitemap.xml

GoodProduction-ready metadata

// layout.tsx — branded and SEO-ready
export const metadata = {
  title: {
    template: '%s — MyApp',
    default: 'MyApp — Ship Better Code',
  },
  description: 'MyApp helps teams ship production-ready code faster.',
  openGraph: { /* ... */ },
  twitter: { /* ... */ },
};

// Custom favicon, 404 page, robots.txt, sitemap.xml
// app/not-found.tsx — custom 404

// app/robots.ts — dynamic robots.txt
