trying to resolve scrolled related clicked bug, added basic pinch selected card stack

TODO:
- scrolled related cards grid still results in visible jump if clicked
- problem is with initial positioning of grid, it supposed to start at
the bottom of screen and continue downwards, instead it is visible on
initial render, distance from bottom correlates to
relatedCardsGrid.scrollY
- basic pinch on selected cards stack, but no going back, and no action
on spread cards
