/*
  Ferheng — "Monument" design system
  Inspired by Taq-e Bostan, the Sassanid rock-relief arch near Kermanshah —
  the historical heart of Kalhorî-speaking Kurdistan. Warm carved stone,
  gold-leaf and manuscript-rubrication red, Kufic display type.

  Shared by every page. Page-specific rules stay in that page's own
  <style> block; anything here is common chrome (nav, header, search,
  result cards, footer) so the whole site reads as one system.
