rwml 0.1.0

//! Robustness + structure harness: run the full pipeline (open → text → model →
//! markdown → html → images) over many `.doc`/`.docx` files, distinguishing a
//! clean [`rwml::Error`] from a real panic (the crate's panic-free contract), and
//! counting the structure produced.
//!
//! ```text
//! cargo run -p rwml --example robustness -- file1.doc file2.docx ...
//! ```
