//! Example: Logging to standard error (stderr)
//!
//! Demonstrates how to configure twyg with:
//! - Output to stderr instead of stdout
//! - Colored ANSI output
//! - Caller information (file and line number)
//! - Trace level logging
//!
//! Useful when:
//! - You want to separate log output from application output
//! - Redirecting stdout to a file while keeping logs visible
//! - Following Unix conventions (diagnostics to stderr)
//!
//! Run with: `cargo run --example stderr`
//! Try: `cargo run --example stderr 2>/dev/null` to suppress logs
