===== 2. Core Architecture =====
- Producer
- Consumer
- Broker
- Message
- Queue
- Exchange
- Binding
- Routing Key
- Virtual Host (vhost)
- Channel
- Connection

===== 3. Exchange Types =====
- Direct Exchange
- Fanout Exchange
- Topic Exchange
- Headers Exchange
- Default Exchange
- Use cases

- Stream queue
- Single Active Consumer

===== 6. Delivery & Reliability =====
- ACK
- NACK
- Reject
- Redelivery
- Prefetch / QoS
- Retry pattern
- Poison message
- Idempotency
- At least once
- At most once
- Exactly once (why hard)
