/* The foam drawer ------------------------------------------------------

   The page is a tool drawer with a two-layer foam insert: a graphite top
   layer over a signal-yellow base that shows only where something is cut
   out. Text lies on the foam; instruments (demos, diagrams, key cards,
   config) lie in pockets cut to their shape. Cuts are flat geometry — a
   hard inner wall, never a gradient. */
