"""
RectPrism Demo - Center/size constructor vs. the FromMinAndMax factory.

RectPrism is a signed-distance leaf primitive: an axis-aligned box. The
regular constructor takes a center point and a full side-length size; the
FromMinAndMax static factory instead builds the same kind of box from its
opposite corners.
