   The demo theme.
   A worked example of a front end, not a framework: every class here is used by a
   template in app/views/site/, and nothing in the CMS depends on any of it. Change
   it, or delete it and write your own — the admin carries on either way.

   The one value that comes from the CMS is --accent (Settings → Look).
