Buffalo Horns in the Storm

The Buffalo variant z -> |Re(z^2)| + i|Im(z^2)| + c iterated over the parameter plane, framed on an isolated mini-copy of the set that stands on the Im c = 0 line so the axis reads as a prairie horizon. Luminance is an exterior distance estimate from the exact real 2 by 2 Jacobian, since the absolute values kill complex differentiability. The distance field here is violently bimodal, so it is equalised against the frame's own measured distribution before the ramp is applied.
