   Tipografia: stack nativa (sem CDN). As fontes oficiais da marca ainda não
   foram fornecidas; ao recebê-las, colocar os arquivos em assets/fonts/ e
   ativar o bloco @font-face abaixo — nenhum outro ajuste é necessário.

   @font-face { font-family:"DiskTrans Display"; src:url("../fonts/xxx.woff2") format("woff2");
                font-weight:700; font-display:swap; }

                font-weight:400 700; font-display:swap; }
   ...e prefixar as variáveis --ff-display / --ff-text com esses nomes.

   Paleta: azul + branco (definido no briefing). Os HEX abaixo são uma base
   sóbria provisória — os valores exatos da marca precisam ser extraídos de
   disktrans.com.br. Ver docs/PENDENCIAS.md.
