/* ==========================================================================
   Nova Aliança Transformações
   Folha de estilo reescrita — monocromática, cantos retos, grid de 12 colunas.
   Tipografia: Archivo variável (eixo wdth 75 para títulos, 100 para o resto).

   Ritmo de fundos da página (faixas de largura total, sem card):
   header branco → hero branco → credibilidade preta → soluções alternando
   branco/cinza (4 blocos) → processo branco com imagem sangrada → atendimento
   nacional cinza → vídeo branco → CTA preta → rodapé preto.
   O preto aparece só duas vezes: a faixa fina da credibilidade e o fecho.
