/* The public pages — the landing page and About us.

   Deliberately not a SaaS landing page. The register is that of a set of
   chambers: a serif for anything that reads as a statement, generous measure,
   restrained colour, and no stock photography of people pointing at laptops. The
   palette is shared with the workspace so that signing in is not a change of
   product. */
