/*
  Chatmail — kayıt sayfası tasarımı (assets/css/kayit.css)
  Fikir: kayıt sayfası ürünün kendisini gösterir. Solda sade form, sağda müşterinin telefonunda
  "sizin markanızın adıyla" gelen WhatsApp mesajı ve e-posta. Firma adı yazıldıkça önizleme canlı güncellenir.
  Palet: adaçayı zemin, nane panel, marka yeşili, koyu orman metni. Tek vurgu: telefon önizlemesi.
  Sınıflar "kt-" önekiyle ayrılmıştır; uyarı ve lightbox stilleri panel.css'ten gelir.
  Hareket: yalnızca sayfa yüklenirken tek bir mesaj dizisi; prefers-reduced-motion'da hepsi anında görünür.
