/* =========================================================================
   STYLE.CSS — design system da Coelho Perícia (direção "Laudo e bancada")
   -------------------------------------------------------------------------
   Conteúdo de leitura em fundo claro, sóbrio como um laudo; o Laboratório e
   o rodapé são uma "bancada" escura, como a tela de um instrumento. A troca
   de fundo sinaliza a troca de atividade: aqui se lê, ali se opera.
   A bancada é qualquer elemento com data-surface="bench": ele redefine os
   mesmos tokens com os valores escuros, e os componentes internos (cards,
   campos, botões) herdam sem precisar de regra própria. Ver ADR 0015.
   Nenhum componente usa cor literal fora deste bloco de tokens, exceto o
   desenho do ERB Lab e o monograma, que só existem sobre fundo escuro.
