  Direção visual: "a software house que parece com a ferramenta que ela constrói."
  Identidade de editor de código / terminal — monoespaçada para títulos, rótulos e
  eixo de navegação; sans para texto corrido. Tema único, escuro — decisão deliberada,
  não omissão: o próprio produto (CRM) também é dark-only, e o vocabulário
  terminal/IDE é convencionalmente escuro. Sem fontes externas (zero dependência de
  CDN, carregamento instantâneo).
