pub fn extract_documentation_html(html: &str) -> StringExpand description
Extract documentation from HTML as cleaned HTML.
Isolates the docs.rs main content area and runs the shared clean_html
pass (removing <head>, scripts, styles, navigation, sidebars, footers,
buttons and source-code links). Unlike extract_documentation, the result
remains HTML rather than being converted to Markdown, so callers requesting
the html format get the documentation body instead of the entire raw page.
