AssetBundleEntries

The shape of an AssetBundle's entry map: a record of friendly key to load path. The keys become the compile-time-checked argument to BoundAssetBundle.get; the values are the paths fed to the loader.

Declared with literal-preserving inference by defineAssetBundle, so a bundle's key union is exactly the keys you wrote — get on an unknown key is a type error, not a runtime throw.
