/* ---------------------------------------------------------------------------
   Portal chrome: glass panels, the sign-in screen, home, and session mode.

   theme.css owns the ambient background. This file owns everything that sits
   on top of it. The glass here is real backdrop-filter rather than a painted
   approximation, which is why theme.css goes to the trouble of putting
   colour variation behind it — a frosted panel over a flat field just looks
   like a grey rectangle.
