   Sorun: iyzico'nun iframe'i, kendi boyutlandırıcısı (iframeResizer)
   çalışmadığında/gecikince ÇOK KISA kalıyor; formun alt kısmı — KVKK onay
   checkbox'ı ve buton — kırpılıyor ("görünmüyor/tıklanamıyor" belirtisi).
   Dışarıdan kontrol edebildiklerimiz:
   - width:100% + display:block → daralma/satır-içi boşluk sorunları biter.
   - min-height:560px → kart alanları + onay kutusu + buton sığar.
     height DEĞİL min-height: iyzico'nun boyutlandırıcısı inline height ile
     BÜYÜTMEye devam edebilir (CSS min-height, inline height'tan küçükse
     kaybeder ama kırpılmaya karşı taban garantisi verir).
   - background:#fff → iframe içeriği şeffaf zeminliyse koyu temada beyaz
     form elemanları kaybolur; iframe'in kendi zeminini beyaza sabitler. */
