"""Cost surface: the cost over two weights, a ball stepping down it.
The surface from the explainer in video/make-it-yours: a tilted bowl with
dents in it, drawn as a checkerboard sheet over a grid floor, a ball on it
with a dashed stick down to the weights it stands for.
Render (the driver does this for every palette; these are for eyeballing):
