On a page inside a new directory (e.g. `get-started/frameworks`), almost* every relative link that went up a level (e.g. `../writing-stories/args.mdx`) now needs to go up two levels (e.g. `../../writing-stories/args.mdx`).
* The exception is relative links pointing to directories that are siblings of the current directory, e.g. on `configure/integration`, a link to `../user-interface/sidebar.mdx` does _not_ need adjusted.
