/* User manual page (user-manual.html)
   Two-column layout: a sticky sidebar (search + collapsible tree, built by
   manual.js from assets/data/user-manual.json) and a content pane whose
   typography mirrors the .legal-doc pattern used on the legal pages. Loads
   last and on its own — this page's layout isn't part of the shared
   per-section cascade the other stylesheets build up. */
