//! Build a synthetic `MultiReport`, render it to HTML, and write the
//! result to disk.
//!
//! Demonstrates the HTML meta-report end-to-end: a passing producer
//! (`dev-bench`), a failing producer (`dev-chaos`), and a producer with
//! warnings (`dev-fixtures`). The output is a self-contained HTML file
//! you can open in any browser — no external assets, no JavaScript
//! dependencies.
//!
//! ```text
//! cargo run --example html_meta_report
//! ```
//!
//! By default the output goes to
//! `target/dev-tools-examples/meta-report.html`. Override with an
//! argument:
//!
//! ```text
//! cargo run --example html_meta_report -- /tmp/meta.html
//! ```
