Output is **byte-for-byte reproducible** (fixed ZIP timestamps), so CI only commits when the upstream docs actually change. +### Table of contents + +The docs page renders its table of contents in a `position: fixed` sidebar, which +e-readers repaint on every page. The tool extracts that TOC into a proper EPUB3 +navigation document (`nav.xhtml`): it shows in the reader's built-in Contents +menu, is the book's opening page, and each entry jumps to the matching section. +The original fixed sidebar (and its dead version-switcher dropdown) is removed +from the content so it no longer bleeds across pages. + +### Well-formedness gate + +Each transformed page is checked for well-formed, balanced XHTML before +packaging; versions that fail are **skipped** (logged as `NotWellFormed`) rather +than shipped as invalid EPUB3. A handful of older docs pages (currently 0.1.1–0.8.1 +and 0.10.x) contain malformed upstream HTML — unclosed `<p>`/`<li>` tags and +outright typos — that can't be repaired without a full HTML5 tree-builder.
