   RESPONSIVE
   The previous mobile-reflow layout (stacked columns, collapsible road
   drawer, horizontal toolbar) has been removed. Small screens now render
   the full desktop (landscape) layout scaled down to fit, driven by the
   fixed-width viewport meta tag in index.html. A dedicated mobile-optimized
   layout will be added later.

   to the screen width; here we cap the full-screen height to a 16:10 landscape
   canvas and center it so the page never reflows into a portrait column. */
