//   - BN exposes getTextureLayerCount(handle) (BabylonJS/BabylonNative#1733), reporting the *bound*
//     layer count: 1 for a single-slice view (layerIndex set), else the underlying array size.

//     baseDepth=depth=layers; layers == 1 -> left as a plain 2D texture.
// C++ wraps whole-array, single-slice, and single-layer native textures and asserts the values
// reported back here.
