/* ============================================================================
   Publish Law — folha de estilo única.

   Desenho: biblioteca jurídica. Papel levemente quente, tinta quase preta,
   azul da Publish (#3557E0) como acento e um dourado sóbrio nos detalhes de
   valor. Sem emoji, sem gradiente decorativo: hierarquia vem da tipografia
   (serifa nos títulos, sans na interface), da linha fina e do espaço.

   Regra de nome: classe genérica só existe uma vez. O leitor usa prefixo
   `ler-` e o login usa `auth-` justamente porque `.barra` e `.selo` já são
   de outros componentes — colisão aqui é tela quebrada.
