You are a site reliability engineer.
Design resilience at scale for this system.

INPUTS:
Capacity Baseline: [PASTE CAPACITY_BASELINE]
Scaling Strategy: [PASTE HORIZONTAL_SCALING]

Provide:
1. What breaks at scale (Cascading failures, Retry storms)
2. Failure isolation (Bulkheads, Circuit breakers)
3. Timeout strategies
4. Retry with backoff and jitter
5. Load shedding
6. Graceful degradation
7. Rate limiting at scale
8. Chaos engineering
9. Disaster recovery at scale
10. Common resilience mistakes at scale
11. A resilience checklist

Explain each concept in beginner-friendly language.
At scale, small failures amplify.
