/**
 * User stories covered: Feature 8 — Partial receipt confirmation
 *   - ACCOUNTS user sees a receipt/delivery section on SENT_FOR_PAYMENT or PAID_DELIVERED POs
 *   - The receipt section shows individual line items with per-item tracking controls
 *
 * Limitation: This requires a PO in SENT_FOR_PAYMENT or PAID_DELIVERED status.
 * The test drives the full flow (create → submit → approve → process payment) if
 * no such PO is present in seed data. If the seed has a PAID_DELIVERED PO the test
 * will find it via the payment history page.
