   SENTINEL COMMAND WALL
   ----------------------------------------------------------------------------
   The operations-room shot from ASTROC_MultiDomain_Showcase: three curved
   primary screens over a strip of operator consoles, lit from the floor.

   Built in CSS 3D rather than as a video so the panels stay crisp at any
   width, the captions stay selectable text, and the whole thing costs a few
   kilobytes instead of a hundred megabytes.
