promo property
Promo is the offer itself. It is fleet-wide, identical for every org — only the two counters beside it move.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
Promo? promo;
