What gets converted
- Every chapter is converted in the book's reading order (the EPUB spine) and joined into one Markdown file.
- Headings, paragraphs, lists, blockquotes, tables, and links are preserved as Markdown.
- The book title from the EPUB metadata becomes the top-level heading; each chapter keeps its own headings.
- Images are reduced to their alt text. The picture data inside the book is not embedded, so nothing is fetched from the network.
