//! WASM compatibility shims.
//!
//! On native targets, async code requires `Send` bounds to work across threads.
//! On WASM (single-threaded), those bounds are unnecessary and will prevent
//! compilation. These traits alias to the appropriate bound per target.
//!
//! Always use [`WasmCompatSend`] and [`WasmCompatSync`] instead of raw `Send`/`Sync`
//! in trait bounds throughout this crate.
