Resilience, Disaster Recovery & High Availability Standard

💡 Copyable AI Prompt Block (AGENTS.md)

<!-- START AGENT-STANDARD: DEVOPS-DISASTER-RECOVERY -->
## Disaster Recovery Rules
- Deploy workloads across multi-Availability Zone (multi-AZ) clusters.
- Validate automated encrypted backups periodically against strict RPO and RTO targets.
- Implement graceful shutdown with `preStop` hooks and connection draining before termination.
