+/**
+ * Payment records (lunar_transactions, stripe_payment_intents) belong to the
+ * Customer (business account) via the Order they're attached to, not to an
+ * individual User, so this is Customer-scope only — same chain
+ * OrderDataProvider already uses (Order.customer_id).
+ *
+ * Like Order itself, payment/transaction records are subject to the same
+ * tax/accounting legal retention argument (GDPR Art. 17(3)(b)) — a payment
+ * record is part of the same financial audit trail as the order it settled,
+ * so this pseudonymizes the card-identifying fields in place rather than
+ * deleting the transaction: amount, status, and the transaction/order link
+ * all remain intact and auditable.
+ *
+ * No Stripe Customer object exists anywhere in this app (see docs/
+ * payments.md "Reconciliation") — there is nothing to request deletion of
+ * on Stripe's side. The only local, erasable PII is the card brand/last-4
+ * on Transaction and the cart_id/order_id/context correlation row on
+ * stripe_payment_intents, which is deleted outright once its Order is
+ * settled (its only purpose was resolving an async webhook callback — see
+ * docs/payments.md "Async resolution" — which has already happened by the
+ * time an erasure request would run).
