   Structure of this file:
     1. Tokens
     2. Reset and base type

   Only edit the tokens in section 1 to reskin the site.

   Typography note: this uses fonts already installed on the reader's
   machine — no webfont download, no third-party request, nothing to
   configure. Georgia is the plain, wide-set serif most academic
   department pages use.
