/* ==========================================================================
   HALFVIM SEGURANÇA PRIVADA, LDA. — FOLHA DE ESTILOS PRINCIPAL
   ==========================================================================
   Este ficheiro está organizado em secções, na mesma ordem em que aparecem
   no HTML. Cada bloco tem um comentário a explicar o que faz e, sempre que
   fizer sentido, o que pode ser alterado manualmente sem partir o layout.

   SISTEMA DE COR (retirado do logótipo/emblema HV e do material de
   marketing já existente da empresa):
   - Preto quase-puro para fundo  → sensação de vigilância nocturna / CCTV
   - Vermelho do emblema          → cor principal da marca
   - Dourado (bandeira de Angola) → usado com moderação, só em detalhes
   - Caqui (cor do uniforme)      → aquece o preto/vermelho, usado em texto
   - Branco-osso                  → texto principal sobre fundo escuro
   ========================================================================== */

     Display  → Anton (condensada, pesada) — para títulos de grande impacto,
                 no mesmo espírito das artes gráficas que a empresa já usa.
     Título   → Oswald — condensada mas mais versátil, para subtítulos
                 e cabeçalhos de secção.
     Corpo    → Barlow — legível, neutra, para parágrafos e botões.
