1//! Parse diagnostics.
2//!
3//! CommonMark has no syntax errors, so markdown-mode parses always return an empty diagnostics list;
4//! the list exists for MDX mode (unclosed JSX tags, stray `<`/`{`, malformed expressions, …)
5//! and for input-level limits.
6//! Diagnostics never abort the parse, an AST is always produced.
