   Billions — Aplicativos e produtos digitais (direção de arte própria)
   Conceito: "Do fluxo ao produto."  Um aplicativo é um fluxo que se testa antes
   de ser construído. Hero com um protótipo navegável feito em CSS/JS, camadas do
   produto e um grafo de etapas com ciclo (prefixo ap-). Exemplo abstrato, sem
   cases de clientes.
