/* ============================================
   CAREER TIMELINE (business.html)
   Vertical timeline at all sizes (newest-first): year | dot | company.
   Mobile: tap a role to expand its story inline (accordion).
   Desktop (>=900px): two columns — timeline left; worked-cities map +
   wide detail panel on the right. Clicking a role lights its city/cities
   and fills the panel below the map. Map visuals mirror contacts (.wm-*).
