   RecreationBench — design system
   Direction: flat instrument dark. The chrome is a thin strip of
   surface colour; every remaining pixel belongs to the two
   desktops being compared. No gradients, no reveals, no
   stagecraft — a bright accent on one channel would bias a
   fidelity judgement, so both screens are framed identically.

   Two shells share this sheet:
     - body.app-shell  fixed viewport, never scrolls (the console)
     - plain body      normal document flow (the admin pages)
