   OKTAN YAPI — components.css  (CSS-A2)
   İçerik bileşenleri. Yükleme sırası: fonts → base → chrome → components → pages/*.
   Yalnızca anlamsal değişkenler (--bg, --surface, --text, --heading, --accent,
   --line …) kullanılır; .theme-light / .theme-dark içinde ikisinde de çalışır.
   Hover efektleri yalnızca @media (hover:hover) altındadır.
   Hover'da yükselme `translate` özelliğiyle yapılır → [data-reveal] / [data-tilt]
   transform'larıyla çakışmaz.
