   BUILDERTRACK — SISTEMA VISUAL "PAPEL & SINAL"
   ------------------------------------------------------------
   Fundo de papel quente, azul da marca BuilderTech e ambar de
   sinalizacao. Sem degrade em texto, sem glow, raio de canto
   pequeno: a pagina deve parecer instrumento de operacao, nao
   landing page de SaaS.

   Duas cores, nao nove. A prancha de marca traz violeta, teal e
   indigo tambem; usar tudo espalha a identidade e devolve a
   aparencia de template que este redesign veio corrigir.

   Dado de frota (placa, km, litro, percentual) sempre em mono.
