   Milieu shell
   The one layout every Milieu app shares: the global bar (served by Milieu
   Central as bar.css/bar.js), an app header carrying the lockup, a left
   sidebar of the app's sections, the main column, and one footer line.

   Requires milieu-tokens.css to be loaded first. Every colour comes from a
   token; the system is one radius, 1px borders, no shadows, and hover shifts
   tone rather than position.
