"""Super-low detail stand-in for the MS12 (MSOP-12) model, built from the dimensions measured on the high model
(provenance/dims-model.json): body box 3.00 x 4.039 x 0.85 mm from z = 0.10, and per lead a flat foot on the seating
plane, a riser and a shoulder into the body, 0.30 mm wide, pitch 0.65, tips at x = +-2.45.
Same frame and colours as the high model (Z up, seated on z = 0, pin 1 at -x/+y); no marking, no pin-1 dimple.
