/* ============================================================================
   login.css — a tela de login do D2Kbal (Web/wwwroot/login.html +
   src/css/pages/login.css), reescrita nos tokens do tema herdado do D2SCI.

   O original era Tailwind puro + um punhado de regras proprias. Como aqui o
   Tailwind compilado e o do D2SCI (nao tem as utilitarias que o D2Kbal usava
   nesta pagina), o layout foi reescrito em CSS proprio — mesma composicao:
   painel ilustrativo a esquerda, formulario a direita, alternancia para uma
   coluna no mobile.

   Todas as cores saem das custom properties do tema (--primary, --card-bg,
   --text, ...), entao a tela de login acompanha o tema Claro/Escuro escolhido
   no modal de Configuracao.
