Round-trip from the Mac/iOS app

A .folio is a macOS package (folder), so it can't be selected directly — in Finder, right-click it → Compress to get a .zip, then choose that here. Links, password, and collaborators stay; everyone's page reloads with the new content.

PDF and Word export need the Mac app (or pandoc) — download the .folio and compile there. Markdown/HTML export runs right here.
