What does cleanup normalize?

The tool standardizes list markers, heading spacing, blank-line density, and trailing whitespace.

Is this safe for existing docs?

The default behavior targets formatting consistency and avoids content rewriting.

Can I review changes before copy?

Yes. You can switch between cleaned markdown, rendered preview, and cleanup summary notes.
