## ADDED Requirements
### Requirement: Live points mall
The mall SHALL display live published points products and the signed-in customer's live points balance, allow redemption with a shipping address, and show the customer's redemption history on the points route. It SHALL replace `INTEGRAL_PRODUCTS` and `USER_STATS` imports on the points route.
#### Scenario: redeem available product
- **WHEN** a signed-in shopper with enough points redeems a published in-stock product
- **THEN** the mall shows the created redemption order and refreshed points balance
