Module normalize 

Markdown-string input normalization — the boundary preprocessing content import runs before parsing. Converts line endings to \n, strips invisible Unicode bidi controls (which sit adjacent to **/_ and defeat delimiter recognition), and repairs <!-- ... --> HTML-comment fences that would otherwise swallow trailing text.

The pure string primitive from_markdown applies at its boundary. It carries no dependency on the document engine, so this crate is a leaf quillmark-core depends on.

Inserts a newline after --> when followed by non-whitespace content.

normalize_markdown
