   The one piece of chrome shared by every page. See client/js/shell.js.

   Typographic note: labels use DM Mono in the register of a spec sheet —
   uppercase, letter-spaced, small. Money and data elsewhere in the app should
   likewise carry tabular figures; `.tnum` below is the shared utility for that.
