/// to write log messages with a minimum level of `Info`.

/// # Panics
///
/// - If the log file cannot be created (e.g., due to permission issues).
/// - If the logger cannot be initialized (which would indicate an internal

/// Call this once, preferably at the very beginning of `main()`, before any
/// logging macros are used.
///
/// # Example
///
/// ```
/// use war_in_tunnels::logs::init_logger;
/// use log::info;
///
/// fn main() {
///     init_logger();
///     info!("Application started");
/// }
