/* Sesli Kalem — Claude Design'daki "Sesli Kalem - Landing" tasarimindan.
   Tasarim dosyasi her seyi satir ici stille yaziyordu; orada dogru, burada
   degil: ayni degerler onlarca yerde tekrar ediyor ve dar ekran icin hicbir
   sey yok. Olculeri ve renkleri birebir aldim, siniflara tasidim.

   Renkler iOS sistem paletinden. Sayfa HER ZAMAN acik temada: tasarim beyaz
   zemin uzerine kurulu ve onizlemesi de oyle. Cihazin koyu moduna uymak,
   tasarimin gormedigi bir sayfa uretiyordu. */
