Bit 18 aliases the top lane-weight bit and bit 12 of the interior probe slot,
so doorway units and probe-lit interior props swayed like trees. A classified
leaf batch's fade-band exile now gets marked copies of its cutout/blend
materials (clutter_fade.z bit 14, FOLIAGE_WIND_MARKER, not a key axis) and
wow_model.wgsl sways only those.
