   PORTFOLIO ATLAS — markers.css
   CHART FURNITURE that sits over the Konva stage as plain DOM:
   the compass rose, the legend cartouche, the zoom control, and
   the first-load intro hint.

   (Waypoints, routes and signposts themselves are drawn inside
   the canvas by map.js — they are not styled here.)

   Consumes tokens from style.css :root.
