facett-markdown/tests/render.rs

//! **CPU render-proof for facett-markdown.** The inline tests cover mention/tag
//! extraction + `state_json`; the `Markdown::ui()` render path (the Edit/Preview
//! toggle, the mention/tag chips, the multiline editor, and the pragmatic Preview
//! renderer) is never executed. This drives real `egui_kittest` frames in **both**
//! modes so the painter runs and the controls ride into the AccessKit tree.
