//! Logging utilities for the text extraction pipeline.
//!
//! These macros forward to the `tracing` crate, which is emitted unconditionally
//! (no feature gate) by every core library in the stack. Callers install a
//! `tracing-subscriber` (or an OTLP layer) to observe the events; without one,
//! the calls are near-zero cost.
//!
//! Each macro accepts two forms for backward compatibility:
//! 1. A single expression: `extract_log_info!(my_string_var)` — logged as `{}`.
//! 2. A format string with optional args: `extract_log_info!("page {}", n)`.
