//! This example demonstrates how to integrate the configuration system

//! with dual-provider support (Databento + Benzinga) into trading services.
|

//!

//! NOTE: This example is currently a stub as the enhanced_config_loader module
|

//! has been refactored. The full implementation requires the provider configuration
|

//! system to be re-implemented in the config crate.
