For Milestone 2: MVP release of QuickView, the feature will be desktop only. This task is to ensure that QuickView is not accessible via mobile skin, and that special:search on mobile skin isn't affected in any way by the SearchVue extension until Milestone 3: Mobile Quickview is released.
Any existing QuickView code for mobile can stay to be used later as long as it does not affect Special:Search on mobile skin at all - this includes both UI and performance. If there is any affect whatsoever, the code will need to be removed (but can be kept locally for future use).
