1// nx_char_asset.nx -- the CONSENT-GATED, LAYERED character pipeline (operator: "license a nude model, add layers
2// of armor/clothing/makeup, deliver into art-coaching / games"). A character = a licensed nude BASE (variant +
3// figure) + a LAYER STACK (nx_outfit clothing/armor, makeup, ...). The DELIVERED nudity tier is set by the layers:
4// a fully-covering outfit delivers CLOTHED (any licensed model), a bare base delivers ARTISTIC-nude (needs the
5// life-drawing license), explicit delivers EXPLICIT. Delivering as a game asset meshes the SDF (nx_meshgen) and
6// writes glTF (nx_gltf_export). Every delivery is GATED by nx_consent (tier + use-case), FAIL-CLOSED. This is the
7// wire-in that turns the consent primitive into real pipeline ENFORCEMENT. license_tier: ORIGINAL
