/* Styles for the crawlable pages under /learn and /contact.

   Deliberately its own small stylesheet rather than the app's 70 KB one. These
   pages exist to be fetched fast by a crawler and read by a person who has not
   signed in, so they load no fonts, no JavaScript and no WebGL — the Atelier
   palette without the machinery.
