Dynamic Routes

Summary

Routes with a variable segment (`[slug]`, `[id]`) that map a single file to many URLs — the basis of blog posts, product pages and user profiles.

• 1Build a `[slug]/page.tsx` route and read the param with the `params` prop.
• 2Learn catch-all routes (`[...slug]`) for arbitrarily nested paths.
• 3Combine dynamic routes with `generateStaticParams` to pre-render known pages.
