 This is the single most important infrastructure decision for cluster stability. All nodes must have roughly the same RTT to each other.

 - **Same region, different AZs** gives uniform 5–30ms RTT and is the validated production topology. Nodes are isolated from AZ-level failures while keeping latency uniform.
