 Adding fonts to `_document` is preferred over individual pages. When adding fonts to a single page with [`next/head`](/docs/api-reference/next/head.md), font optimizations included by Next.js will not work on navigations between pages client-side or when using [streaming](/docs/advanced-features/react-18/streaming.md).
