+//! Internal tracing utilities for conditional debug and trace logging.
+//!
+//! This module provides macros that conditionally compile logging statements
+//! based on the presence of test, tracing, or prod-logging features.
 
-// Static variable for one-time initialization
-pub(crate) static LOGGING_INIT: std::sync::Once = std::sync::Once::new();
+// Note: These macros are currently unused but kept for potential future use.
+// They provide a pattern for conditional compilation of logging statements.
 
-// Debug macro for conditional compilation
-macro_rules! debug {
-    ($($t:tt)+) => {
-        #[cfg(any(test, feature = "tracing", feature = "prod-logging"))]
