   Loaded after site.css (and pages.css) by every workflow layout and by the
   order pages. Tokens only; the one literal colour is the keyword `black`
   behind video.

   Surfaces are separated by tone, never by outline:
     canvas   --fog    main background on .app-surface
     panel    --paper  .card
     well     --fog    bands and nested panels on a panel
     lead     --suite  .lead, the one dark panel that says what to do now
   Tables and form fields keep their lines (site.css).
