Responds to bot review comment suggesting the overflow error message could be misleading when element count overflows before byte count is computed.

Analysis

The current implementation is correct. When nrows * ncols exceeds usize::MAX:

  • For ZST (elsize == 0): Error message correctly reports element count overflow
  • For non-ZST (elsize > 0): Byte count necessarily exceeds isize::MAX, so the error message accurately describes the constraint violation

No code changes required. The error messages in Overflow::Display are accurate for all overflow scenarios.
