A new version starts as a copy of another. One publish puts every version live.
Languages share one page tree: each page can be translated into the site's other languages, in the editor beside the original or with AI (a page, the changes since the original moved on, or every missing page, within the plan's monthly allowance). One publish puts every language live. Readers get /docs/site-name/es/…, a language menu, untranslated pages in the original with a note, per-language search and sitemaps, and the reader's own words from the reader packs. Export, import and Git sync keep each language in its folder.
