+            "Durable execution enables long-running waits (5 minutes for warehouse processing, 3 minutes for carrier pickup) without consuming compute resources.",
+            "Each step is automatically checkpointed, allowing the workflow to survive interruptions and resume from the last successful step.",

+            "Order state is persisted in Amazon DynamoDB with real-time status updates throughout the 17-step workflow."
