/**
 * The settings menu's "Download ePub" entry, or `null` for none.
 *
 * The item used to be unconditional and its URL derived from the project name, so a site
 * that built no ePub (the default) shipped a menu item that 404s, and a multi-volume site
 * or one with `basePath` or `epub.title` linked to a file nothing wrote (#218). The site
 * build now bakes the list of volumes it makes into the page config:
 *
 *   - a list   → one item (or, for several volumes, a submenu), at the build's own URLs
 *   - `[]`     → the site makes no ePub: no item
 *   - no key   → a hand-written `config` that predates this: the old derived link, unchanged
