Customer basket sizes
Mechanic
The basket target and bulk-purchase chance grow with shop level. Budgets, available stock and product limits can reduce the completed sale.

Bulk purchases
Rich customers use twice the base bulk chance, capped at 100%. The bulk generator starts with a random 1–13 items, then has a 50% chance per continuation to add another 0–13. It allows at most 32 continuation steps and returns at least one item.
Ordinary basket calculation
The target mean is adjusted for a 5% rich-customer share and a bulk mean of 13.5. Let p be 95% of the ordinary bulk probability plus 5% of the rich bulk probability. The ordinary basket contains 1 plus a Poisson roll.
Its mean parameter is max(0, (max(1, target mean) − p × max(1, 13.5)) ÷ max(0.001, 1 − p) − 1). If p reaches 0.999, that parameter becomes zero.
Budget headroom is 1.25 for ordinary customers and 1.4 for rich customers.
