/* ==========================================================================
   TUDOUTIL — DESIGN SYSTEM v2  ("Papel & Tinta")
   --------------------------------------------------------------------------
   Este arquivo é carregado DEPOIS de todos os outros CSS.
   Ele faz duas coisas:
     1) Define os tokens novos da identidade visual.
     2) Faz a "ponte" com as variáveis antigas (--blue, --card-bg, --text...)
        usadas pelas 41 páginas de ferramenta e pelo blog.
        Resultado: o site inteiro muda de cara sem reescrever 41 arquivos.
   --------------------------------------------------------------------------
   Conceito: fundo de tinta (ink), superfícies de papel, acento CITRINO.
   O citrino (#CBF24E) é a assinatura: nenhum concorrente de PDF usa.
