//! Zero-cost profiling verification tests

//! These tests verify that profiling has truly zero overhead when the feature is disabled.
//! They only run when the profiling feature is NOT enabled, ensuring that profiling code
//! is completely removed from the binary at compile time.

/// 1. The profiling feature gate is working correctly
/// 2. No profiling code is present in the binary
/// 3. The build succeeds without profiling dependencies

/// If this test runs, it means the profiling feature is properly isolated.
