/* ==========================================================================
   ASSINATURA VISUAL DLB — Veios de Mármore (VERSÃO DE TESTE)
   --------------------------------------------------------------------------
   Aplica os padrões gráficos da marca (assets/Padrões) como transições
   sutis entre as seções, usando apenas pseudo-elementos CSS.

   Arquivos utilizados (todos com fundo transparente):
   - 03.png ................. veios ESCUROS  → usados em fundos claros
   - 6.png .................. veios DOURADOS → usados na seção Zhaire (sand)
   - Padrão DLB Branco.png .. veios BRANCOS  → usados em fundos escuros

   Princípios:
   - Opacidade baixa (0.04 a 0.12) para nunca competir com o conteúdo
   - mask-image em gradiente: o veio "nasce" na divisa entre seções e
     desvanece para dentro do bloco, como se atravessasse a transição
   - pointer-events: none + conteúdo elevado com z-index → zero impacto
     na interação e na leitura
