   Kaynak: teslim edilen prototip (sticky-makale.html + rev-liste.html)
   Prototipin düzeni birebir korundu; renk/tipografi/ölçü marka kitine çekildi.

   PROTOTİPTE DÜZELTİLEN DEĞERLER
     --y  #F4FA0A → #F5FB0A   (#F4FA0A geçersiz renk listesinde)
     ink  #131313 → #191919
     mut  #6E6E6A → #6B6B66
     ln   #E4E4E1 → #DCDCD8
     soft #F7F7F5 → #F4F4F1
     font Helvetica Neue → Archivo

   SARI KURALI YORUMU (onayınıza sunulur)
     Sarı yalnızca üç yerde: 3px okuma çubuğu, bülten bloğu zemini ve
     imza oku diski. Prototipteki sarı METİNLERİN tamamı kaldırıldı:
     istatistik rakamı, "BUNU HÂLÂ BİLMİYORUZ" etiketi, avatar harfleri,
     buton oku, menü altı çizgisi, içindekiler aktif çizgisi.
