Ticket Number Mapping

Displayed ticket numbers are a scrambled one-to-one mapping of draw positions, so sales volume can't be inferred while tickets are on sale. The mapping seed is revealed after the draw, letting anyone recompute the draw position behind every displayed ticket number and confirm the winners above.
