 * The provider never reads a gift card from the database. The Apply Gift Card
 * workflow (server-side data nodes, the only lookup) leaves what the shopper
 * may see — `{ id, last4, balance, currency, checkedAt }` — in localStorage,
 * and this code only displays how much of the order that balance would pay.
 * The place-order workflow re-reads the row and debits it; nothing here is
 * trusted for money.
 *
 * A tender is never a discount: the order total is unchanged, and the six
 * `Cart` keys this feeds (`giftCardApplied`, `giftCardLast4`, `giftCardAmount`,
 * `giftCardAmountPickup`, `amountDue`, `amountDuePickup`) exist on every store
 * so a page can bind them regardless — a store without the feature reports no
 * card and an amount due equal to the total.
