# The `--cfg direct_wasm` flag activates the `#[wasm_bindgen]` bindings in
# `src/wasm.rs` (gated behind `all(direct_wasm, target_arch = "wasm32")`),
# producing the JS bindings and the .wasm artifact in ./pkg. Only the
# identification / catalogue / metadata layer is exposed (not the message model).

# Usage:
