### F. PDF-Rechnungsgenerierung & Mail-Versand (Post-Processing)

- **Snapshot-Exklusivität**: Die Rechnungsgenerierung erfolgt ausschließlich auf Basis der in `orders.order_data` und `orders.customer_data` eingefrorenen Snapshots.
|
||||
- **Entkopplung & Asynchronität**: Die Generierung der PDFs und der E-Mail-Versand sind vollständig aus dem synchronen Checkout-Flow entkoppelt. Der Checkout liefert dem Frontend sofort nach Speicherung in der DB eine Erfolgsmeldung zurück. Die Generierung und der Versand werden asynchron im Hintergrund (via unblockiertem Promise-Worker) ausgeführt, um SMTP-Latenzen abzufangen.

Updates/Inserts der Rolle werden ausschließlich von der `service_role` (Backend Admin-Client) akzeptiert, um Privilegien-Eskalation zu verhindern.
