span_slack and af_snoise each spelled 2^-14 (value) and 2^-12 (gradient) inline, in C# and
HLSL. Both now read the constants beside SNOISE_HESSIAN (math.Affine.cs, CultMath.Affine.hlsl,
Unity copies), so a device-judged widening moves every reader. Bits unchanged. The test
oracles in AffineTests and GlslMirrorTests read the constants; a new test pins af_snoise's
allowance to span_slack's terms. span_slack's comment no longer claims it is the only
allowance. Does not build green yet: CultMath.glsl is not regenerated in this commit.

(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).
