   nexus-ui.css — componentes e estrutura do Nexus (Central + Estoque).

   Carregado POR ÚLTIMO, depois do CSS da página, usando só os tokens de
   nexus-tokens.css. É só aparência: não cria, remove nem muda nenhum elemento.
   Para voltar ao visual anterior, basta tirar o <link> deste arquivo e do
   nexus-tokens.css (os CSS das páginas continuam funcionando sozinhos).

   CAMADAS (de trás para frente, todas bem distintas):
     página (--nx-bg)  <  cartões (--nx-surface)  <  realces (--nx-surface-2)
     menu lateral = azul vivo próprio · barra do topo = faixa clara com sombra
