+/**
+ * Server-side client for the real IIOS service (see D:\iios\docs\IIOS_API_AND_SDK_GUIDE.md).
+ * Runs only in BFF route handlers — never shipped to the browser. Auth uses a dev token
+ * minted from /v1/dev/token (requires the IIOS service running with IIOS_DEV_TOKENS=1);
+ * in production swap mintToken() for a real Session-Broker exchange.
