   THE MET LADDER — MoveLab's set piece (AAA+++ §5)
   The drawing hand is SQUARE TERMINALS and nothing else in the ring uses it:
   butt caps on the bars, square caps on the axis, a hard 10x10 stop block whose
   RIGHT EDGE lands exactly on the value, crisp edges everywhere, zero radii.
   Round caps belong to fuel, butt-nib to burn, 1.6px round to yoga, plate rules
   to fly, filled silhouettes to cook, pictograms to gym, katori units to thali,
   rectilinear bezels to sehat. This is a machinist's stop on a ruled field card.
   Fixed viewBox, so it reserves its own space: CLS 0.00.
