Okay, I know all of that stuff is only temporarily hardcoded until we support
multiple sections, but could we at least pull this value out to a constant?

Actually, I don't think getChildAt() is the right method to use, as that's going
to be the third current child of the RecyclerView, regardless of what view that
is. Couldn't we just use findFirstCard().itemView?
