Counts retain their source-reported units. Additional rows can describe components, paired items, or derivative copies and are not automatically added to the primary quantity.
Notes
The current Zenodo deposit contains one 68,401,895-byte archive with 410 source PNG images, 410 corresponding masks, 20 repeat annotations, and one linked workbook. The version-specific dataset DOI is 10.5281/zenodo.18779434 and the concept DOI is 10.5281/zenodo.17570502. Reference 35 in the published article lists 10.5281/zenodo.17570504, which resolves to an unrelated record; the article's Data Records section and the official deposit identify 10.5281/zenodo.18779434.
