+    #   15      the top's own black front edge -- the row the lid
+    #           replaces, so it opens the fascia the way Bill's row 16

+    #           desktop's own rim, so `fascia` (it wraps every side)
+    #   18-21   the base -- the left leg (the @#@ at x0-x2), the open
+    #           apron between, and the DRAWER PEDESTAL at x20-x31: two
+    #           #555 drawer fronts (rows 16-17 and 19-20) in a black
+    #           frame, which the measured recess pass sinks a voxel
+    #           each because they are non-black regions sealed behind
+    #           their own black outline. Row 21 is the ground line, and
+    #           the measured 22 is where the drawing puts the cast
+    #           shadow on the floor -- 22-23 are that shadow, dithered
+    #           floor in the walkable cell, and the model builds none
+    #           of it.

+    # for band, so it takes that part table with x and rise adjusted:
+    # rows 20-21 the backrest top seen from above, 22-31 its elevation,
+    # rise = -7 putting it back on the floor, z 22 depth 10.
