interface BandSeeds
One derived seed per band, kept on the sketch.
elevationAt used to call deriveSeed twice per sample — a string hash per
band per sample, on a function that runs five thousand times per patch. The
seeds depend on the surface and nothing else, so they belong with the rest of
what the surface derives once.
