   DOSSIÊ DR · VSL + CRIATIVOS 7D/MÊS — sistema de design
   MANIFESTO (fable-web-craft · Ato 1)
   1. TESE: arquivo de inteligência de guerra × mesa de engenheiro de
      conversão — papel de arquivo com fichas numeradas e carimbos, que
      abre painéis-blueprint escuros quando o assunto vira mecânica.
   2. SENSAÇÃO: "isso foi extraído de 14 horas de gente que fatura 7
      dígitos, e cada frase tem a prova ao lado".
   3. GESTO: o chip de timestamp ▶ [hh:mm:ss] clicável em cada
      afirmação, que abre o segundo exato do vídeo-fonte.
   4. ANTI-REFERÊNCIAS: dashboard dark de SaaS · slide de curso com
      ícone 3D · landing de guru com gradiente roxo.
   5. APOSTA: papel claro num nicho onde tudo é dark; display serifado
      itálico gigante; blueprints escuros como contraponto de ritmo.
