Markdown TOC Generator

H2 (##), H3 (###) and H4 (####) headings are extracted. H1 (#) is omitted because it is typically the page title and is not normally listed in a table of contents.

Yes. Lines inside fenced code blocks (``` or ~~~) are skipped even if they look like headings, so example markdown in your code samples won't pollute the TOC.

Anchors follow the GitHub convention: the heading text is lowercased, whitespace becomes hyphens, and punctuation is stripped. Unicode characters such as Japanese, Korean, or Chinese are preserved as-is.
