expected.json `continuity`: over the tangent seams wholly within `within_mm`
of `near`, the curvature jump across them (exact surfaces, 65 stations a
seam) at most `curvature_jump_per_mm` clear (`clear_mm` along the seam) of the
vertices where two of them turn, where a neighbour's own G1 seam ends.
07/015, the box corner's three r5 rounds with corner: g2: one valid body of 10
faces within the box, its patch's twelve seams jumping at most 1e-3 per mm
clear of the hole's six corners by 1.2 mm (2.7e-4 measured; the ball corner
of 009 jumps 0.2). Its golden entry is the passing run's.
