FICTIONAL EXAMPLES. Three invoices, each supplied as PNG and JPG. These are two encodings of the same invoice, not six different invoices. Choose ONE format per invoice for a batch test. These clean images were rendered from designed PDFs; they are not camera photos or measured extraction results. Compare with invoice-line-items.xlsx: source references use equivalent HTML filenames with the same stems. Invoice totals: ALD-1048 USD 693.00; BCN-2206 USD 252.00; HBR-709 USD 495.00. Six line items in total. Test real photos, poor scans and multipage invoices separately.
