/* PLANO
   Conceito: placa e faixa de sinalização — o vermelho do letreiro da fachada sobre preto asfalto,
   com amarelo da frota como marcador e uma linha tracejada de pista como detalhe-assinatura.
   Direção: Urbano enérgico (cantos 6-10px, contraste alto, números grandes, itálico pesado como o letreiro).
   Paleta: vermelho #af413d · preto asfalto #271319 · cinza #54565b · amarelo frota #f6c91c · superfície #f6f3f1 · branco.
   Fontes: pilha do sistema (download das fontes web falhou nesta sessão); títulos em peso 800, caixa normal, H1 itálico.
   Hero: B (split) — foto da fachada é 4:5 e pequena demais para sangrar; moldura vermelha deslocada + etiqueta de endereço.
   Seções: hero · categorias (placas A/B/AB) · como funciona (linha do tempo numerada, fundo escuro) ·
   o que os alunos destacam (nota + lista) · estrutura (2 fotos) · FAQ · contato.
   Assinatura: linha tracejada de pista (.roadline) e placas quadradas com a letra da categoria. */
