   Longtom — the public site.

   Layout only. Every colour, font and radius comes from
   tokens.css, which is the app's own stylesheet copied in at
   build time rather than reimplemented — the site and the
   product are the same object and should not drift apart.

   The app is a dense console at 14px. A page somebody reads
   once, on a phone, in a browser tab, is not, so the reading
   scale is larger here and nothing else changes.
