 internal **Wormhole menu**, preserving the underlying application's focus.
 
+With a reader supporting Tentacle settings registration, global Preferences →

+Save persists the two checkboxes and returns to reader preferences; Escape
+discards the form's edits. This entry point works without the Wormhole CLI.
+Rebuild both the reader and Tentacle to obtain settings registration and the

 Install the `magic-wormhole` CLI using your distribution's package manager.
