Optionaloptions: GltfLoaderOptions
The IO and decode seams plus the §96 bounds; all optional.
A loader producing GltfAssets. Each call returns a distinct loader object, hence a distinct cache slot — hoist it to a module constant, exactly as with createTextureLoader.
Builds a §78 glTF 2.0 loader for the AssetManager (§96, §33).
See the module header for the exact tier — what parses, what is refused by name, and what is ignored with a record. The result of a load is a GltfAsset; assembly into scene nodes is
four'sinstantiateGltf, because this package may not name a node (§3.1).
