   TASARIM YÖNÜ — "sinematik endüstri"
   ------------------------------------------------------------------
   Rakip/ödüllü endüstri sitelerinde işi yapan şey tipografi değil,
   GÖRSEL. Bu sürümün omurgası:

   1. Tam taşan fotoğraf   — kahraman alan sayfa kenarına akar.
   2. Bento ızgara         — eşit kart dizisi yerine farklı boyda
                             hücreler; ikisi fotoğraflı.
   3. Aydınlık zemin       — beyaz taban, tek koyu dramatik bölüm.
   4. İri tipografi        — başlık mimarinin kendisi.
   5. Ölçülü hareket       — yalnızca görünüme girme; video/parallax yok.
