/* The explainer figures (js/cme-explainer.js), used by /what-is-a-cme and the /learn modules.
   Loaded after help.css (tokens). A figure is a dark "stage" holding a real image or a drawn
   canvas, an optional row of controls, and a caption.
   The .article rules are for /what-is-a-cme alone (the only page here with an .article): it
   sets the site's text measure to the figures' width, so every block shares the same edges.
   The /learn pages do the same in css/learn.css. */
