   Hero — "Fikir sizden, <kod/> bizden."
   · Açılış perdesi (.intro): tüm ekranı kaplar, derleme sayacı 100'e
     ulaşınca yukarı doğru açılır
   · Tam ekran sahne: solda başlık, sağda canlı yazılan kod editörü ve
     kodun derlediği gerçek proje önizlemesi
   · İmlece tepki veren nokta ızgarası (canvas)
   · Kapanış: aşağı kaydırırken sahne küçülüp kartlaşır, satırlar ayrışarak
     yukarı süzülür, editör geriye yatar. JS --p (0→1) değişkenini yazar.
