/* ASI-20 field unit, printed flat.
   The 3D housing was dropped on Vadim's review of 2026-10-27: a photoreal shell cut into pieces
   cannot follow a column that grows with the content (the flanks were upscaled 1.63x and tiled with
   a seam every 163 px, eighteen of them down the page). What carries the register now is the
   drawing, not a render: hairline frames, corner brackets, a stencil face, the olive and amber inks
   measured off his picture, and the same warm ground it stood on.

   One type scale:    16 / 20 / 24 / 32 / 44   (16 is the floor, his own order of 2026-09-13)
   One spacing scale: 4 / 8 / 12 / 16 / 24 / 32 / 48
