//! Tracing compatibility layer.
//!
//! Re-exports `tracing`'s `debug!`, `info!`, `warn!`, `error!` macros when
//! the `tracing` feature is enabled and provides no-op stand-ins when it
//! is not. Callers `use crate::tracing_compat::{debug, info, warn, error}`
//! and write feature-agnostic code; the no-op variants compile to nothing.
//!
//! The `#[tracing::instrument(...)]` attribute is gated separately at the
//! call site via `#[cfg_attr(feature = "tracing", tracing::instrument(...))]`
//! because attributes cannot be re-exported.
