The enhanced exterior WMO point-light term evaluated falloff per fragment but used the
flat lamp selection of the provoking vertex (snapped to its 33 yd MCNK cell), so a large
wall or paving triangle took one vertex's whole lamp pool and neighbours differed: long
straight-edged dark wedges on Stormwind's gate ramp and yard walls at dusk/night. Ranks
the closest exterior lamps at the fragment (static_gx + fallback wow_model), shared by
the shadowed and unshadowed evaluations. Classic (all light gains 0) keeps the vertex
pick and its packed frame bits; capture scenarios stormwind-training-yard-*/gate-ramp-*.
