• GiftCard.purchaseId (UUID) — the purchase that created the gift card; the same ID returned by purchaseGiftCard and getUserPurchases. Returns null if no associated purchase. (FLUZ-18308)
• GiftCard.purchaseDisplayId (String) — the short, human-readable Fluz transaction ID (e.g. 1047283) that support references in manual reviews and exports. Returns null if no associated purchase. (FLUZ-18308)
• GiftCard.purchaseValue (Float) — the face value (denomination) the gift card was purchased at, in the card's currency. (FLUZ-18325)
• GiftCard.currentValue (Float) — the remaining balance on the gift card; equals purchaseValue for single-use cards. (FLUZ-18325)
• GiftCard.currency (String) — the ISO currency code of the gift card's value (e.g. USD). (FLUZ-18325)

All five fields are now returned by getGiftCards (and anywhere GiftCard is exposed), enabling order/value reconciliation without calling revealGiftCardByGiftCardId per card. Additive and backward-compatible.
