# XWUILoyaltyPointsTracker

A loyalty/rewards points tracker: the current point balance and tier, a progress bar toward `data.nextTierName` (shown when `data.pointsToNextTier` is set), and a list of redeemable rewards - each with a "Redeem" button disabled when the balance doesn't cover its cost. Redeeming deducts the reward's cost from the balance locally.

## Events

| Event | Callback | Subscriber | `detail` |

| `xwui-loyalty-points-tracker:redeem-reward` | `onRedeemReward` | `onRedeemReward(handler)` | `{ rewardId }` |
