1//! Corre una app WASM Tier 3 dentro de una ventana Llimphi real.
2//!
3//! El `.wasm` está embebido (compilado por `scripts/build-wasm-demo.sh`). El
4//! host no sabe nada de la app: pide `wasm_view`, materializa el `WireNode`,
5//! rebota clicks y rutea el teclado al input enfocado. Toda la lógica vive del
6//! lado guest.
7//!
8//! `cargo run -p llimphi-wasm-runner --example run_counter --release`
