about
nx_gltf_export_gate.nx -- prove the glTF/.glb export (roadmap R7, VRM foundation): mesh a bestiary variant,
write a binary glTF, and validate the container: magic "glTF" + version 2 + total-length == filesize + a JSON
chunk (with a POSITION accessor of the right vertex count) + a BIN chunk. This is a REAL interchange format
(three.js/Unity/Godot/Blender import it), the step up from STL/OBJ toward riggable VRM avatars. expect_exit:0
