xtask/tests/demo_goes_the_container_road.rs

//! **`cargo xtask demo-wasm` / `deploy-pages` go the container road** (THE LAW: a
//! build thing builds in a container or a KVM, never on the host).
//!
//! Until 2026-09-30 they called `nornir_pages::demo_wasm(&cfg())`, which ran HOST
//! `cargo build --target wasm32…` and the HOST's wasm-bindgen. Now they hand edda
//! nornir's declaration and a row name, and edda builds that row in the pinned image.
//! nornir declares no demo row yet (the set is pinned to the five matrix atoms), so
//! the verbs are REFUSED BY NAME — held here, without an engine.
