   LAYOUT  —  the machine chassis.
   A 7 x 4 grid: a 10px frame of crosshair corners, a 120px header row split
   into identity / three nav cells / a composite cell, then a 250px sidebar
   next to the scrolling main panel. The container is painted with ink so the
   2px gaps read as manufacturing seams.
