}Notes
- Source: GO4's status endpoint returns the order time, the main status and a detail line, and the delivery time. It has no scan list, so the result holds the order and, once delivered, the delivery.
- Time zone: read as
Europe/Bratislava. When the order time is later than the delivery time, the "Ordered" event is left out so events stay newest first.
