//! Native-target stub verification.
//!
//! `mediadecode-webcodecs` is `wasm32`-only: on every other target
//! the crate compiles to an empty module so workspace `cargo build`
//! / `cargo check` keep working in native dev loops. This test
//! confirms that empty-stub behavior — the crate links, exports
//! nothing, and importing it doesn't drag in any wasm-only types.
