1//! # LogLevel
2//!
3//! Resolves the logging level for the application.
4//!
5//! ## RESPONSIBILITIES
6//!
7//! ### Log Level Resolution
8//! - Read RUST_LOG environment variable
9//! - Apply default log level based on build type
10//! - Resolve final log level for logging initialization
11//!
12//! ## ARCHITECTURAL ROLE
13//!
14//! ### Position in Mountain
15//! - Early initialization component in Binary subsystem
16//! - Provides log level configuration
17//!
18//! ### Dependencies
19//! - log: Logging framework
20//! - std::env: Environment variable access
21//!
22//! ### Dependents
23//! - Fn() main entry point: Uses resolved log level
24//!
25//! ## SECURITY
26//!
27//! ### Considerations
28//! - No security impact (logging only)
29//!
30//! ## PERFORMANCE
31//!
32//! ### Considerations
33//! - Log level resolution is fast
34//! - Correct log level reduces logging overhead
