Case contract

Input fields name, street, city, region, postal, country (destination) and origin. Toy templates: AA "{city} {region} {postal}", BB "{postal} {city}", CC city and postal on separate lines with the city uppercased; unknown destinations use AA. Each rendered line is whitespace-collapsed and empty lines are dropped. When origin differs from destination the destination name (or its code when unknown) is appended.

Why this case matters

Cross-border labels must follow the destination order; misplaced or doubled components delay or return shipments.

One recorded failure
