The button leaves the header bar for the world, centered on the columns the next purchase unlocks and panning with them until it leaves the view. Those columns now take a lighter tint than the locked ground behind them, so the boundary between the two says how far one purchase reaches. Nothing in the code reported a scroll: the camera knew it had moved and told only the hover. A ViewScrolledEvent says it now, which is what a widget keeping a place in the world rather than on the screen needs. The panels want none of it -- they are placed against the screen and stay put as the world moves under them -- so the button is placed after their pass and never joins the rectangles they step around. Its face is two lines, "Expand" over the cost. That makes the cost a display of its own, so it carries the building-block tooltip the way every other item value does, on hover alone since the click buys the expansion.
