/* Black Track — site publico (blacktrack.org).
   Sistema visual: paleta do painel (azul-marinho, tinta, linhas, fundo cinza-claro, azul de acao) e a pilha
   de fontes do sistema. Assinatura da marca: o traco em degrade do logo (azul -> roxo -> rosa), usado so onde
   ele representa o caminho do anuncio ate a venda (jornada no painel, passos de "How it works").
   Tipografia so por tokens (--fs-*, --fw-*): pesos 400/500/600/700 existem em qualquer fonte estatica
   (Arial, Segoe UI), entao a hierarquia e a mesma no Windows e no Mac. 280/720 ficam so na marca nominativa
   e na dupla leve/negrito dos titulos do hero e do CTA.
   Sem estilos inline nas paginas: a CSP em _headers bloqueia atributos style. */
