/* 08-whatsapp.css — Conversa no WhatsApp dentro do iPhone.
   Os arquivos css/ são carregados em ordem numérica pelo index.html: a ordem importa (cascata). */
/* ---------- Conversa no WhatsApp (iPhone 3D) ----------
   Recria o WhatsApp dentro da mesma moldura do iPhone 17 Pro Max do rastreio:
   cabeçalho com "digitando…", papel de parede, balões com hora e tiques, campo de
   mensagem onde as mensagens do cliente são digitadas antes de enviar.
   As mensagens ficam no HTML (sem JS a conversa aparece inteira); o script
   "Conversa no WhatsApp" esconde e revela uma a uma. Quadro fixo 380x640,
   reduzido com zoom (--k) para o texto ficar nítido. */
