/*
     * Note: the `dlpack.h` header suggests/standardizes that `data` must be
     * 256-byte aligned.  We ignore this intentionally, because `__dlpack__`
     * standardizes that `byte_offset` must be 0 (for now) to not break pytorch:
     * https://github.com/data-apis/array-api/issues/293#issuecomment-964111413
     *
     * We further assume that exporting fully unaligned data is OK even without
     * `byte_offset` since the standard does not reject it.
     * Presumably, pytorch will support importing `byte_offset != 0` and NumPy
     * can choose to use it starting about 2023.  At that point, it may be
     * that NumPy MUST use `byte_offset` to adhere to the standard (as
     * specified in the header)!
