   header.css — üst şerit, ana başlık, menü ve dar ekran çekmecesi.

   Kendi kendine yeten dosya: başlıkla ilgili HER kural burada.
   main.css içinde başlık kuralı bırakılmadı.

   Yapı kararı — önemli:
   Çekmece (dar ekran menüsü) <header> ETİKETİNİN İÇİNDE DEĞİL, KARDEŞİ.
   Daha önce içeride olduğu için başlığın kapsayıcı bloğuna ve iç içe
   geçmiş kabuk genişliğine takılıyor, panel eziliyor/taşıyordu.
