gtin resolve
Looks up a barcode number across Open Food Facts and a general product database, returning product name, brand, category, packaging, quantity and images where present. The check digit is computed locally before anything is queried: an invalid number is a typo, and reporting it as not found would send the caller looking in the wrong place.
