Start with tuney/app/app.py at start() and tuney/midi/midi.py at port and start(), then reproduce the Windows failure around mido.open_output(). Review how the frozen app handles MIDI startup and identify the expected behavior when MidiOutWinMM cannot create an output port; done should include coverage for that failure path.
