//! Distributed tracing integration for observability and debugging.
//!
//! This module provides tracing setup and configuration for Tako applications using the
//! `tracing` ecosystem. It configures structured logging with file names, line numbers,
//! log levels, and span events. The tracing system helps with debugging, monitoring,
//! and understanding application behavior in development and production environments.
