I think it's unusual that the menus for the fragmented view are the responsibility of the fragment on the right, as it adds complexity to the logic

I would expect the menu to be extracted out of the fragments, and extended to the full width of the activity (with the activity being responsible)

You would then have two menu files for the DeckPicker (fragmented/non), and one for the Options (non-fragmented), and not need to worry about conditionally applying text, or moving some of the processing to the fragment
