   Redesign editorial: paleta off-white/azul acinzentado/azul profundo,
   ocre como accent pontual. Serif (Fraunces) nos títulos, sans (Work Sans)
   no corpo. Tema claro é o padrão da marca; tema escuro segue o sistema do
   visitante (prefers-color-scheme) ou a escolha manual salva no navegador
   (ver main.js), sem nunca depender de JS pra pintar a cor certa primeiro
   (os tokens do tema escuro também respondem à media query sozinhos).
