## Notes

- Prefer explicit, runtime-native startup configuration for operational clarity.
- Use provider-specific helpers in each runtime (`AddDurableStackPostgres` in .NET, `createDurableStackPostgres(...)` in Node.js).
- Keep secret values (connection strings, tenant/client secret) in secure secret stores.

For defaults and detailed semantics, see [Configuration options](configuration-options).
