/* Oizi · landing
   Rolagem como narrativa, no jeito das páginas de produto da Apple: cada cena fica presa
   na tela enquanto a rolagem a transforma (a tela do app sobe, a frase acende, os canais
   voam para a caixa, a conversa acontece, a câmera entra no app, a galeria corre de lado).
   Sem script ou com movimento reduzido, tudo aparece no estado final, sem prender nada. */
