//! Validation helper: dump SEGB record structure (state, timestamp, payload
//! length) — NOT payload content. Run against a real Biome SEGB file (e.g.
//! `App.MenuItem`) to reconcile `segb-core`'s container parse with the
//! `ccl-segb` reference.
//!
//! Usage: `cargo run -p segb-core --example dump_structure -- <segb-file>`
