+//! This module provides a separate reexport of the [`ThreadAware`] trait, which is also
+//! available at the crate root. The purpose of this module is to allow downstream crates
+//! to selectively reexport just the trait without also bringing in the [`ThreadAware`]
+//! derive macro (which is conditionally exported at the crate root when the `derive`
+//! feature is enabled).
