Detailed Description

Periodic images are a UNION -- the oversized-leaf trap, gated.

A container wall built as slab-minus-cavity in a periodic box: if the slab is wider than the box,
its periodic images overlap and refill the cavity wherever a neighbouring image's slab covers it
(the query takes the min over images). set_solid_from_scene must (a) DETECT it exactly --
periodic_image_overlap_cells() > 0 plus a stderr warning -- for a 0.7 L slab, and (b) report 0
for a slab of half the box plus the wall thickness, whose cavity must then be the full 53 cells.

Usage: PYTHONPATH=<flow build> python periodic_image_gate.py
