Edit the content (Markdown) in all three languages, then set a new guest password and download the updated file. The language tabs below switch which translation you're editing.
How rotation works: This file has all three languages baked in, encrypted together with the current guest password. When you download a new version, it re-encrypts everything with your new password. Save the file over the old one, upload it wherever you're hosting, and send the new link + password to your next guest.
