   editorial typography (2026-05) — aplica em todo o site
   stack: Inter em tudo + DM Mono (mono)

   Em 30/08/2026 a Fraunces saiu do site inteiro por decisão do Fernando:
   o site passou a usar uma fonte só. A variável abaixo continua se chamando
   --fb-font-serif porque ela é referenciada em 6 arquivos de CSS; o nome
   ficou, o valor virou Inter. Se um dia voltar uma serifada, é aqui que ela
   entra e o site inteiro acompanha.
