/* Comparative Advantage (economics/comparative-advantage.php). Uses the shared graph styles in
   market-graph.css (controls, badges, axes) with its own stage: the two countries' diagrams side by
   side, then the controls and the readouts. On a laptop the controls and readouts share one scrolling
   column; on a wide desktop they get a column each. Under 900px it all stacks and the page scrolls.
