   To switch to Galdien (Craft Supply Co) later: it is a licensed font, not a
   Google font, so it has to be self-hosted. Buy the WEBFONT licence from
   fontspring.com or myfonts.com, drop the files into assets/fonts/ with the
   names below, uncomment the @font-face block, then add 'Galdien' to the
   front of --font-body and update the footer credit in index.html.
