+ * This is intentionally separate from Prisma: Prisma remains the app's primary ORM and owns the
+ * `passenger` schema via `DATABASE_URL` (see prisma.service.ts). This second connection exists
+ * solely because `@tria-plc/api-common` / `@tria-plc/iamapi-common` are TypeORM-based and the
+ * `JwtGuard` reads `iam.sessions` through a TypeORM `DataSource`.
+ *
+ * Consumed by `TypeOrmModule.forRootAsync` in app.module.ts.
