Detailed Description
Non-owning read view over a pair of DataVariant streams representing interleaved vertex bytes and a flat uint32_t index array.
Parallel to VertexAccess and TextureAccess: describes what the data IS in memory terms with no knowledge of Vulkan, Portal, or concrete vertex structs (MeshVertex). The layout field carries full semantic description via VertexLayout::for_meshes(), including stride and attribute offsets.
Ownership contract: the two DataVariant instances and the optional RegionGroup must outlive this struct. MeshAccess holds raw pointers and spans into their storage.
Zero-copy: both vertex_ptr and index_ptr point directly into the storage of their respective DataVariant. No conversion buffer is needed because MeshInsertion always writes the canonical 60-byte interleaved format before producing a MeshAccess.
Submesh structure: when the source file contains multiple meshes, submeshes holds a RegionGroup named "submeshes". Each Region maps to one MeshSubrange and carries name, material_name, and vertex_offset as attributes. Single-mesh files leave submeshes as nullopt; the entire index buffer is one contiguous range.
