(c) is FogField.DeepWell (ruling wells-scale-order-of-magnitude), measured under
the centred-warp interval bound and the affine bound on the same seeds; the
shallow wells are the printed (c-band) row. The warp-enlarged ball and the
warp-carrying detail ball in FogField.Bound are gone. (c) asserts affine cheaper
than the centred interval at both warps, with the 0.5 cull floor under both
(ruling affine-wells-contract-cheaper-than-interval).
