) -> DyadPlacementExpand description
Compute an illustrative placement of a fetal mesh within a host frame: centre it at the host
centroid, scaled so its largest extent fills fill (0..1) of the host’s smallest extent (so it sits
inside). Pure. Illustrative only — see the module note on scale registration.
