7/// (encoded `.voxj` blocks) with fixed position and sample encodings, ready to
8/// serialize with [`to_voxj_file_bytes`](crate::to_voxj_file_bytes). Each
9/// object's palette cell counts come from the palettes it references; the
10/// palettes, hierarchy, roots, and `ext` carry over unchanged. Errors if an
11/// object references a palette outside the document's `palettes`.
