        This is carefully balanced--  the minimum width at which the GUI will be displayed is 1024px.
        At that size, the stage pane is 408px wide, with $space of padding to each side.
        However, we must also add the border width to the stage pane. All-in-all, the stage pane's final width is
        408px + ($space + $stage-standard-border-width * 2) (one border & padding per left/right side).

        @todo This is in place to prevent "doubling up" of horizontal scrollbars in narrow windows, but there are likely
        much better ways to solve that (e.g. undo #2124, remove this flex-basis entirely). However, they run their own
        risks of breaking things, so let's just leave this as-is for the time being.
