//! Crate-internal observability macros.
//!
//! Behavior:
//! - `tracing` feature => emit `tracing::*` events (preferred when enabled)
//! - `logging` feature (without `tracing`) => emit `log::*` records
//! - Neither enabled => macros consume variables via `format_args!` but produce no output
//!
//! This ensures that variables passed to logging macros are always consumed,
//! preventing `unused_variable` warnings when observability features are disabled.
