             out to the technical sister site.

   Design tokens.

   Deliberately unlike the sister site, which is warm-neutral with a brown
   accent and a system sans throughout. This one is cooler, uses a serif for
   body text, and reserves sans for interface furniture. A reader landing on
   both should not have to check the URL to know which they are on.
