/* The shell (PLAN 3.12): the app grid, the shell bar, the navigation pane in
   its three modes (open, rail, overlay), the command palette, the company
   picker, the person's menu, notifications and the shortcut sheet - plus the
   sign-in page. Everything around a screen, nothing in it.

   Colours, radii, shadows, layers and motion come from tokens.css (PLAN
   3.2-3.5). Where a token is new in wave 1.1 its value is repeated as the
   var() fallback, so the shell reads the same before and after tokens.css
   gains it; the fallbacks can go once every branch has the new tokens. */
