+/**
+ * Zahlungsart "PayPal Checkout (Orders v2 / REST)".
+ *
+ * Neues, eigenstaendiges Modul – laeuft parallel zum Legacy-NVP-Modul
+ * (PaypalPaymentMethod) und teilt sich mit ihm KEINEN Code.
+ *
+ * Aktivierung ueber einen eigenen Eintrag in `payment_methods` mit
+ * module = 'paypalrest'. Der Cashdesk instanziiert dann automatisch diese
+ * Klasse (ucfirst('paypalrest').'PaymentMethod' => PaypalrestPaymentMethod).
+ *
+ * Flow: after_order() legt die PayPal-Order an und leitet den Kunden zur
+ * Approve-URL weiter. Der Rueckweg laeuft NICHT ueber den Cashdesk (der ist auf
+ * das Legacy-Modul verdrahtet), sondern ueber /core/paypal_v2/return.php.
