//! Profiling harness for session execution overhead.

//! Run with samply:
//!   cargo build --example profile_execution --features embedded --release
//!   samply record ./target/release/examples/profile_execution

//! Or with a specific iteration count:
//!   samply record ./target/release/examples/profile_execution 5000
