A2 ONLY. Built from current good 2B-compatible base: 02_same_plus_reference_header_safety.
Goal: match head/face color to the now-correct body/torso without touching A2 body texture 350d703c or any 2B files.
No IDs changed, no WMB changes, no material refs changed, no container/table redesign.
Test: 03_BOTH_HEAD_SKIN_ALBEDOS_from_reference
Both likely head/skin albedos from the good-looking reference. Strongest color-match attempt, still no body or ID changes.
