       DESIGN SEED:
       Font: Fraunces (display, optische serif) + IBM Plex Sans (body)
       Kleur: Aards/naturel - groen domineert structuur, crème geeft
              ruimte, geel schreeuwt precies één keer per sectie.
         Dominant: #00AE41  Ruimte: #F5EAE4  Accent: #FEF577
         Tekst:    #1A1A18  Mid:    #3D3D38   Licht:  #6B6B62
       Layout: Full-bleed magazine secties - elke sectie heeft
               eigen achtergrond + binnenste kolom-layout
       Textuur: Harde schaduwen - geen blur, puur offset (4–6 px)
       Toon: Onvermijdelijk
