   Lightweight stylesheet for docs.pixbob.com (the hub
   homepage only). Tokens are copied from PixBob Font Studio's
   own docs stylesheet (fontstudio/style.css) so this page
   feels like the same ecosystem without importing any of the
   sidebar/search/content-section machinery that page needs
   and this one doesn't.
