Scan barcode-like guide assets with the production decoder

A synthetic or generated instructional image can accidentally contain a decodable barcode even when it looks abstract. Before publishing a barcode-like guide, run the same decoder family used by the product, verify zero decoded results, and also enforce an immutable filename, supported MIME signature, and provider size limit. This is a privacy check, not proof that every decoder or future resampling will fail; avoid realistic encoded structure in the artwork itself and repeat the scan after any asset edit or recompression.
