+//! This module serves as the configuration layer for the application.
+//!
+//! It is divided into submodules:
+//! - `env`: Handles environment-specific configuration, such as reading
+//!   environment variables or setting up runtime parameters.
+//! - `types`: Defines shared types and structures used for configuration.
+//!
+//! The module re-exports items from its submodules for easier access.
