The button leaves the header bar and floats over the world, centered on the columns the next purchase unlocks. Being a place in the world rather than on the screen, it pans away with those tiles; nothing needs to bring it back, since the leftmost pan centers the buildable edge and the columns lie just left of it. Those columns now take a tint of their own, more transparent than the locked ground behind them, so the boundary between the two says how far one purchase reaches. The tinted area itself went undocumented until now, and it has no left edge: expansions are unbounded, so the tint runs as far left as the view can see, which is what made "the middle of the greyed region" answerable only for the next expansion's slice. The button's face becomes two lines, "Expand" over the cost. That makes the cost a display of its own, so it carries the item tooltip the way every other item value does instead of the whole button standing in for it.
