The live screen opens wide beside the chat while the bot works on it or asks for a takeover, a file the bot presents as its result opens next to the conversation, and a question that scrolled away gets a "Needs you" pill back to it. Shared core rules derive the focus from signals clients already have (pointer events, takeover requests, a new `present` flag on attach_file, pending asks), move the pane only on focus edges, never replace a pane the user opened, and learn per bot whether the screen opens on its own. Pane widths persist per device; mobile shows a pill that opens the computer.
