   Palette is cool and institutional; the one accent is a deep pine used only
   for confirmation and primary action. Anything the machine produced — a
   reference number, a duration, a count, a config key, a log line — is set in
   monospace. That is the whole visual rule, and it is what ties the reference
   on an error page to the same string in the log viewer.

   No webfonts: the checkout path should not make a third-party request, and
   the container should not need the network to render.
