I wonder if a low-level, grind over the blue line with a narrow-ish window
computation is the right way to do that? Perhaps something like count up
how many of a few dozen "features" are or are not present might work
better? Seems more cognitively plausible.

For example, having any pointy bits versus having none is a much more
trenchant difference than having four versus six points.
