 * Meshy exports bake the albedo into the EMISSIVE channel (the same texture as baseColor, factor
 * [1,1,1]) so previews pop without any lighting — in-world the character self-glows at full
 * brightness and a moody scene can't touch it. Strip emissive ONLY on that signature (an authored
 * emissive mask is a distinct texture and survives), and on those materials drop the textureless
 * metallic=1 Blender default to 0 — with the glow gone it would render as black chrome under
 * punctual lights, when the baked look is plain rough albedo.
