alternatively could looks for the intersecting bounding boxes of all targets

Both work well... but without any depth/thickness the chance of intersection are null...
extruding the plane to a volume on a known axis, e.g z here (no rotation) is trivial but limiting.
Could rely on the bounding sphere instead but not ideal when text is beside other pieces of text
Note that in practice we plan to bring geometry with the text, a la Scratch, to showcase grammar and potential to combine.
Consequently those problems would probably go away by intersecting with that geometry instead.
That still means an efficient solution, e.g convex hull or BVH

generalize selector to pick last Nth rather than very last

display result in 3D HUD with rotating objects and selector value
ideally themselves also selectable/usable, e.g clone from HUD to bring back "out"
requires extra work as becoming a child will not work, own positionning
should fix that
could compare to world coordinates instead of "just" position attribute
add a clear selector function to avoid making the HUD unusable
could also pick via volume, e.g wireframe box
start with https://threejs.org/docs/#api/en/math/Box3.containsPoint
can iterate with https://threejs.org/docs/#api/en/math/Box3.containsBox
