/* ---------------------------------------------------------------------------
   Fabula One documentation.

   The tokens are the landing page's, which are the app's. Light is the printed
   page, dark is the editor, and both grounds come from the product — so the
   site, the docs and the thing they describe are visibly one object rather
   than three designs that happen to share a name.

   One stylesheet for every page, linked rather than inlined: there are ten
   pages here and one of them is generated, so a change to the type scale must
   not mean ten edits and a rebuild.
