draw the system at three zoom levels.

الموضوعات المخطط لها

• Level 1, context: your system, its users, and external systems.
• Level 2, container: separately running units (services, databases, brokers) and how they talk.
• Level 3, component: the main building blocks inside one container.
• Level 4 (code) is usually left to the IDE.
• Each element has a name, a type, a short description; each arrow a label such as "Publishes OrderPlaced (Kafka)".
• Diagrams as code: Structurizr DSL, PlantUML C4, or Mermaid; verify version of the C4 support before recording.
