+> - To minimize charges when idle, set `--min-replicas 0`. The service scales to zero and doesn't allocate compute when not serving requests.
+> - The first request after scaling to zero incurs a cold start. To avoid cold starts, keep at least one warm replica by setting `--min-replicas 1` (or higher), trading steady-state cost for lower latency.
