/* ============================================================================
   Cidade Simples — site institucional
   Conceito: "Guichê aberto". O site é organizado como um balcão de
   atendimento bem sinalizado: cada bloco responde uma pergunta que o cidadão
   faria ao atendente, com passos numerados, linguagem simples e cada serviço
   marcado pela sua cor (a mesma faixa colorida que o app usa nos cards).

   Paleta e tipografia vêm de constants/colors.ts (tema claro do app) — nenhuma
   cor nova foi inventada aqui.
