What is the documentation issue?

https://nextjs.org/docs/pages/getting-started/fonts#with-tailwind-css

This is the Pages Router documentation, however, it applies the Fonts using App Router mechanism.

The links referenced on the page also sometimes lead to /docs/pages/* and sometimes to /docs/app/*.

Is there any context that might help us understand?

There is no Layout component at app/layout.tsx in Pages Router.

Does the docs page already exist? Please link to it.
