   CSS 100% escopado sob o prefixo .dcx- (zero seletores globais, zero
   !important). Os tokens --dcx-* são aplicados pelo motor a partir da
   config — que referencia as variáveis do PRÓPRIO site, então o assistente
   acompanha o tema claro/escuro automaticamente. Fallbacks = hex reais do
   tema escuro (auditoria do Passo 0).
