   aynı dosya), gece ve gündüz paletleri (gokyuzu.css'teki data-sky değerleri), altın
   vurgu ve "şu an" bandı renkleri uygulamadan alınmıştır. Telefon çerçevesindeki ekran
   çizim değil, uygulamanın kendisidir (site/uygulama/, bkz. uygulamayi-yenile.js);
   pusula, zikirmatik ve ufuk yayı oradan gelir, burada yeniden çizilmez.
   Gök cisimleri (güneş, hilal) bu sayfada ÇİZİLMEZ: yalnız uygulamanın kendi yayında görünür.
