   Side panel, version 4: one continuous sheet instead of stacked cards, and a panel that folds into a
   slim rail so the maps get more room. Loaded after styles.css, so it overrides the earlier panel rules.
   The wide-screen rules sit in a media query: on a phone the panel stays a drawer (see styles.css).
