Fonts aren't loaded on docs site.

Looks like primer searches for fonts in the root directory but we serve the docs site from a sub directory.

Reproduce the font-loading failure on the docs site and inspect how Primer constructs font URLs when the site is served from a subdirectory. Trace the relevant asset path from the docs entry point; done means the deployed docs site loads its fonts without requesting them from the repository root.
