/* Sérgio Ruiz — advogado | Direito das Sucessões e Planejamento Patrimonial
   Identidade real: roxo #6B4367 / mostarda #E28F26 / cinzas #666868 · #898989
   Sistema: hero/header/footer em tom profundo (plum-charcoal), corpo de conteúdo em creme claro.
   Tipografia: Plus Jakarta Sans (estrutura/institucional) + Fraunces itálico (acento humano/legado).

   Tema dia/noite: NOITE (padrão) = roxo lidera nos elementos estruturais/texto de destaque,
   mostarda oculta em preenchimentos (botões/badges). DIA = inverte a liderança — mostarda passa a
   liderar texto/estrutura, roxo assume os preenchimentos. As superfícies (header/hero/footer escuros,
   conteúdo claro) permanecem as mesmas nos dois temas — só a cor de marca líder muda. Os tons de
   "ink" (texto) usados aqui foram escurecidos/clareados especificamente pra manter contraste AA nas
   duas direções — nunca usar os hex crus da marca como texto pequeno sobre fundo claro/escuro. */
