 * SOURCE mesh (BVH) -> source UV -> bilinear sample of the source texture. Layered surfaces (hair shell
 * over scalp) are disambiguated by preferring source triangles whose facing agrees with the target
 * triangle when their distances are comparable. Unwritten texels are dilated outward into gutters so
 * bilinear/mip filtering never bleeds background into charts. Base color only — imports carry a single
 * baked atlas by contract (the conform pipeline drops other maps).
