nornir-demo/src/main.rs

//! **nornir-demo** — nornir's live web + native demo GUI.
//!
//! The nornir zone/jera showcase surface ([`ZoneDemo`]) mounted on the reusable
//! [`facett_wasm_demo`] harness: one surface, two hosts, from the same source —
//!
//! - **native:** `cargo run -p nornir-demo`
//! - **wasm:**   `cargo xtask demo-wasm` (build) / `cargo xtask deploy-pages` (publish),
//!               served at <https://nordisk.codeberg.page/nornir>
//!
//! [`ZoneDemo`] gives nornir the SAME common zone/jera framework korp runs (L5 —
//! consume the shared widgets, never hand-roll): a central
//! [`facett_zoneui::JeraCentral`] jobs/zones/infra panel + a 🧰 Tools-menu →
//! [`facett_zoneui::ZonePane`] (default demo zone). The pre-existing release
//! dependency-DAG panel ([`ReleaseDepDag`]) stays reachable via the View menu
//! (additive, no regression). There is NO bare "demo" button. It is its **own**
//! crate — NOT wired into `nornir` / `nornir-server` (`publish = false`).
