   Demo marking — shared across every interactive surface that
   runs on sample data (workbench, ART·13 bench, 24·72 clock).

   Two layers, deliberately hard to miss and hard to mistake for
   a live system:
     .demo-wm   — tiled diagonal DEMO watermark over the viewport
     .demo-chip — an explicit chip for the app's own top bar
   Both are inert (pointer-events: none) and print with the page.
