1//! Client configuration structures for different cloud platforms
2//!
3//! This module contains the configuration structs for all supported cloud platforms.
4//! These structs define the authentication and platform-specific settings needed
5//! to connect to cloud services, but do not contain implementation logic (which
6//! remains in the respective client crates).
