   Folha de estilo única do site — compartilhada por todas as páginas.
   --------------------------------------------------------------------------
   Layout, cores e componentes seguem o site original. As classes têm os
   mesmos nomes do HTML original (.hero-slider, .feature-card, .btn-whatsapp…)
   para o markup continuar reconhecível.

   O que foi acrescentado: componentes que as páginas internas de SEO precisam
   (breadcrumb, texto de artigo, tabela técnica, FAQ, calculadora), todos
   desenhados na mesma linguagem visual — navy #1a1a2e, laranja #f7931e,
   Poppins, cantos 10px, botões pill.
