/* guide.css — layout for the style guide (/style-guide.html).
 *
 * The page loads the stylesheets it documents (style.css, blog.css, pages.css, home.css, lists.css)
 * and its specimens use their classes unchanged. This file only lays out the page around them.
 * The two .stock panels need paper and night stock on screen together, so they carry a fallback copy
 * of the style.css colour tokens; a script on the page refreshes them from the live file. */
