/* K13 Design & Code (js/duo13.js): the two-player co-op platformer on the workbench. Tokens come from css/site.css.
   The card, head, reset pill, status line and footnote reuse the .wb rules in css/workbench.css and the bench subgrid;
   this file only adds the stage (HUD strip on top, board in the middle, controls underneath) and the panel.
   The canvas lives only inside .d13-view, and every button lives below it, so nothing can cover a button. */
