//! Optional tracing subscriber initialization (feature-gated: `logging`).

/// Initialize tracing subscriber for applications using dravya.
///
/// Uses the `DRAVYA_LOG` environment variable for filtering (defaults to `warn`).
/// Safe to call multiple times — subsequent calls are no-ops.
///
/// Note: this is a convenience for binaries. Library consumers should
/// configure their own subscriber; dravya emits standard `tracing` events.

    use tracing_subscriber::EnvFilter;
