facett-syschart 0.1.19

//! **syschart_panel** — the [`facett_syschart`] architecture/topology map mounted on
//! the reusable [`facett_wasm_demo`] host: the [`SystemChart::demo`] constellation (a
//! small nordisk architecture grouped by layer — ingress `gateway` → the
//! `korp`/`nornir`/`holger` services → the `skade`/`iceberg` storage, with dependency
//! edges and per-service badges) rendered as a **native window** and a **wasm / WebGL
//! canvas** from the same source, ready for a Codeberg-Pages site (the harness recipe
//! in `facett-demo/README.md`). Click a service chip to expand its detail.
//!
//! - native: `cargo run -p facett-syschart --example syschart_panel`
//! - wasm:   `cargo build -p facett-syschart --example syschart_panel --target wasm32-unknown-unknown`
//!           then `wasm-bindgen … --target web` it and serve with the generated
//!           `index.html` ([`facett_wasm_demo::IndexHtml`]).
