Keep temporary keyboard profiles separate from saved bindings. Add optional persistent mouse capture with ordered release/focus/reset handling, and let offline sources represent an unplugged port without falling back to physical input. Existing capture and source defaults remain intact. Beads: beads-9wg8 and beads-eio.19.18.
Non-Windows only reconciled while focused AND captured; focus loss drops capture, so a release outside the window left activation_down_ stuck. Decision moved to LocalMousePolicy::sync_left (tested).
