//! Smoke tests for allocation measurement support.
//!
//! These tests run only with `--features count-allocations` because the feature
//! installs the allocation-counting global allocator. Hot-path allocation
//! budgets live in `benches/allocation_hot_paths.rs`.

#![cfg(feature = "count-allocations")]
