 * A non-Swapped payment method (e.g. Cash App Lightning) rendered inside the

 * shared list machinery (sort, sectioning, slicing, empty-state) unchanged, but:
 * - `fopType` is a plain token (NOT a backend `FormOfPaymentType`) used for
 *   priority ordering and, via `getFopKey`, as the row's stable identity,
 * - `embeddedFlowUrl` is always empty (no embedded Swapped flow),
 * - `paymentMethod` is the marker the type guard keys off.
