+Open **Project sharing** to connect to `pace_server`, upload a private snapshot,
+grant reader/writer access, and download another user's project. Uploads require
+the revision you downloaded; stale writes keep your edits and show a conflict.
+Downloads are staged for review before replacing the open project. Tokens stay
+in memory and are cleared on reload. Local save/recovery works without a server.
+See [setup and the two-client walkthrough](docs/project-sharing.md).

+This is **project sharing, not real-time co-editing**. There is no automatic
+upload, merge, polling or live presence.

 Projects currently use **`pace-editor-draft`, version 1**, an explicitly

+Draft files remain `.pace-draft.json`; core conversion, preview and game export
+require a separate integration that can account for their different features.
