## Why

The mall exposes a fixed points-store page and a fixed points balance. A real points mall needs a dedicated redemption order lifecycle and must consume the customer-account ledger rather than treat points as an unguarded profile field.

## What Changes

- Add platform-managed points products with localized catalog content, integer point price, stock, availability, and images.
- Add points redemption orders and immutable redemption-line snapshots, separate from cash orders and payments.
- Debit points and decrement redemption stock atomically; reject insufficient points, inactive products, and unavailable stock.
- Seed demo spendable points only through the archived customer-accounts credit path (immutable entry); do not treat seed as an earning campaign.
- Add customer browsing, redemption, and redemption-history APIs; add platform product and redemption-order management; replace mall fixtures.

## Capabilities

### New Capabilities
- `points-mall`: Points product catalog and atomic customer redemption orders.

### Modified Capabilities
- `frontend-mall`: Points mall and balance surfaces use live APIs.
- `frontend-admin`: Platform operators manage points products and redemption fulfillment.

## Non-goals

This change does not grant points, accept cash co-payments, share normal SKU inventory, add coupons to redemptions, or add customer withdrawals.

## Impact

Depends on archived `customer-accounts`; adds Rust points module/migrations, shared contract/locales, mall and admin routes, and points-redemption integration tests.
