/* =========================================================
   TARİHÇE — dört kuşaklık hikaye.
   A quieter register than the process pages: the story
   itself carries the drama, so the direction here is
   editorial and calm. One new idea: the spine gradient runs
   from a faded chart-teal (the sea, where the story starts)
   down into copper (the metals trade it becomes today).
