Hmm, "Unknown Shape TGeoCompositeShape" in convert-to-step...
Removed volumes extruding out of mother volume by increasing some dimensions. Now looks like this in ZOY ortho view: 
There was a hidden vacuum volume that is now also fixed, so finally overlaps succeed: 
For reference, this is the world before, which is clearly more than necessary (and it's all air, not vacuum):

Good point! Maybe sharpening up the world for those is useful then.

A question here is whether this is best done as a standalone feature (i.e. celeritas -> edm4hep) or if it makes more sense to get this 'for free' by running...
I don't think the ROOT aspect of DD4hep is something celeritas needs to worry about, since this would be *another* way of providing the geometry (and the standard gdml way...
