//! Benchmark: Measure overhead of core type construction and serialization.
//!
//! When observability (tracing) is wired, this benchmark will measure
//! span creation overhead. For now it benchmarks message construction
//! and serde roundtrip as a baseline.

#![allow(clippy::unwrap_used, clippy::expect_used, clippy::panic)]
// Benchmark harness provides its own main.
#![allow(missing_docs, unused_results)]
