   (852 × 562). Renkler o görselden ölçüldü (29 Eylül):
     lacivert #01172F → #05213D (sağ üst), sarı #F8BB2A, ayraç #1F3756,
     sağ alt beyaz #F3F6FB, ✕ #0C131D. Sol panel %57 (x = 485 / 852).
   Masaüstü: ortada modal + karartma. ≤ 600 px: alttan kart, karartma yok,
   fotoğraf ve özellikler yok, ekranın en fazla %35'i (Google'ın mobil araya
   giren pencere kuralı).
