/* ================================================================
   Human Journey Lab — "Explorer's Journal" Design System
   ================================================================
   Concept  : An academic explorer's field journal — scholarly yet vivid.
              Think National Geographic meets modern editorial design.
   Fonts    : Playfair Display (editorial headers) + Inter (clean body)
   Palette  :
     --primary:    #2C3E50  deep navy
     --secondary:  #E67E22  amber orange
     --accent:     #16A085  teal green
     --bg:         #FDFEFE  clean white
     --text:       #273746  dark blue-grey

   Unique features vs all other sites in this project:
   1. Dot-grid CSS background on hero (radial-gradient, no image)
   2. Expedition numbered badges on article cards (CSS counter)
   3. Vertical timeline layout on articles list page
   4. Auto-generated floating section-dot navigator on article pages (JS)
   5. Teal reading-progress bar (fixed top, fills on scroll in articles)
   6. Fade crossfade slider (not slide/transform)
   7. Amber ornamental divider line between page sections
