   One illustration, one question, one line of reassurance. This domain hosts
   several unrelated things behind their own logins, and none of them are
   listed here — so the page's whole job is to look like somewhere you'd want
   to be let into, and then get out of the way.

   System fonts throughout: the office network blocks Google, and Google Fonts
   would be blocked with it.
