   Mesmos tokens do site institucional (361digital.com.br), estendidos com um
   tema claro. A alternância black/white é feita trocando as variáveis dentro
   de .sec-dark / .sec-light — os componentes (botão, card, tag, formulário)
   leem sempre as mesmas variáveis, então funcionam nos dois modos sem
   duplicação de CSS.
