//! Tight loop for profiling LocalLeaf archive ingest vs heap-Leaf.
//!
//! Build/decode N tribles in a loop, alternating heap and archive
//! ingest. Run under samply / cargo flamegraph to pin down which
//! function dominates the archive-path time.
//!
//! Usage:
//!     cargo build --release --example archive_load_profile
//!     samply record ./target/release/examples/archive_load_profile
