/* ============================================================
   vanBaarsel.net — token system
   Concept: night navigation. A compass + topographic contours,
   because the site's actual content (geocaching) is about
   finding your way. WP01 / WP02 markers are real waypoint
   labels, not decoration.

   Theming: all colors are tokens, so the page can switch between
   a "night navigation" dark theme and a "daytime map" light theme
   automatically, based on the visitor's system/browser setting
   (prefers-color-scheme). No toggle needed — it just follows them.
