# Module: Azaion.Common.Configs.ConnectionStrings

## Purpose
Configuration POCO for PostgreSQL connection strings, bound from `appsettings.json` section `ConnectionStrings`.

## Consumers

- `ASPNETCORE_ConnectionStrings__AzaionDb`
- `ASPNETCORE_ConnectionStrings__AzaionDbAdmin`

## External Integrations
None.

## Security
Contains database credentials at runtime; values must not be logged or exposed.
