/*
  THESIS: o amigo oculto é um bilhete de festa da turma; o sorteio se revela rasgando o canhoto.
    Visual de bilhete, mas o texto nunca diz "rifa" (a turma acharia que é rifa de verdade).
    Recusa o cartão de Natal verde e vermelho e o painel genérico de cartões brancos.
  OWN-WORLD: chão azul-cobalto com retícula; bilhetes amarelo-sol com trama guilhochê, picote e recortes;
    tinta azul-marinho; carimbo rosa-choque; números de série em Big Shoulders.
  STORY: abre o convite do grupo, entra com o Google, monta a lista; no dia, rasga o canhoto e vê quem tirou.
  FIRST VIEWPORT: título gigante "AMIGO OCULTO" em branco e amarelo no cobalto; logo abaixo, um bilhete
    "CONVITE" com o botão "Entrar com Google" no alcance do polegar.
  FORM: bilhete / ingresso de festa (6º da lista), seed 4b6661e6.
