"""Negative test helper: move selected objects of the open doc (inside Rhino 8, via runner).

Globals: __rhino_doc__, PIER_ID, MOVES = [{"id": "BS08"} | {"mark": "P2"}, "d": [dx, dy, dz]}, ...],
optional UNDO (move back by -d). A `mark` selector moves the first occurrence (sorted) of that mark,
centreline and pipe together. Prints what was moved; raises if a selector matches nothing.
