        geometric center lands on the BottomActionBar's real on-screen
        rect — reported as the bar "intercepting pointer events" for
        content that's actually just been squeezed out of its own
        viewport. The floor keeps the scroll region a real, usable size;
        on the rare device/zoom combination where total content still
        exceeds the viewport, the page falls back to ordinary
        document-level scrolling instead of corrupting hit-testing for
