   KURALLAR
   - Renk / boşluk / yarıçap / gölge değerlerini doğrudan yazma, token kullan.
   - --color-accent-green (#6A9F2F) ASLA metin rengi değildir. Beyaz üzerinde
     kontrastı 3.18 — yalnızca grafik öğe, ikon ve halka motifi için.
   - Logo yalnızca açık zeminde. Koyu bantta beyaz kart içine alınır.
     Header ve favicon: tarihsiz logo. Hero/footer/OG: tarihli logo.
   - Mobil menü kırılım noktası 1280px — main.js'teki DESKTOP_BREAKPOINT ile eş.
