Subject: [PATCH] fix: restore toLowerCase() in handelize + align tests with
 post-#501 behavior

- Restore .toLowerCase() in handelize (was dropped somewhere, tests expect it)
- Update dimension-mismatch test to expect throw instead of silent rebuild
  (matches new behavior from #501)
- Fix one stale test expectation for preserved dots in filenames
