/*
 * Açılır pencere (sheet). Üç karar:
 *
 * 1. SABİT DEĞİL, ESNEK YÜKSEKLİK. Kısa form kısa kalır, uzun form ekranın
 *    tamamına kadar büyür ve içeride kayar. Her formu tam ekran yapmak, üç
 *    alanlık bir formu boş bir panelde yüzdürürdü.
 * 2. BAŞLIK VE DÜĞMELER SABİT, ORTA KISIM KAYAR. Kaydırılabilirliği anlatan
 *    asıl işaret budur: düğmeler yerinde dururken içerik altlarından akar.
 *    Ayrıca "Kaydet" hiçbir zaman ekran dışında kalmaz.
 * 3. SİLİNME YALNIZ GEREKİNCE. Düğmelerin üstündeki solma, aşağıda okunmamış
 *    içerik varsa çıkar, sona gelinince kaybolur — yoksa sürekli duran bir
 *    süs olur ve hiçbir şey anlatmaz.
 *
 * Konular geç geldiği için pencere boyu sonradan değişiyor; solmayı bu yüzden
 * MutationObserver da tetikler (bkz. sheet() / kaydirmaIzi()).
