nx_assetvariant.nx

nx_assetvariant.nx -- SWAP-AS-DATA v0 (swap+motion census SCOPE A, the DnD/game ask): reuse ONE synthetic base asset (person / wolf / goblin) and produce MANY variants by SWAPPING slots -- head (plain/horns/snout), ears (none/pointy), tail (none/tail), build (slim/normal/bulk radius scale). A VARIANT IS DATA: the tuple {species, head, ears, tail, build} fully determines the SDF part list, so a bestiary row = a tuple, and diversity = enumerating tuples -- no hand-crafted one-offs. Fills the nx_sdfrender base (parts/npart/kblend) exactly like sdf_body/t2mesh, so every variant renders on the SAME photoreal-path shader and can feed nx_meshgen -> STL for game assets. Neural face/clothes swap on IMAGES = the S5 rung; this is the parametric spine (like t2mesh before Shap-E). license_tier: ORIGINAL
