   bandeirinhas coloridas (SVG) balançando no alto, presos nas pontas da fita. Abas laranja (ativa) / roxa como as do Ranking;
   e-mails em cartões brancos (o novo com fundo dourado claro e selo NOVO); a carta aberta num papel com borda de carta aérea
   e linhas de caderno. Palco fixo 1280x720 escalado: sem media queries.
