/* feira — estilo. Mobile-first; tokens claro/escuro via prefers-color-scheme
   (os mesmos do datahidro/levabici). Tipografia: IBM Plex Mono vendorada
   (lib/fonts/) pra marca, rótulos e números; texto corrido em fonte do sistema.

   Cor de marca = cmocean.phase, a paleta cíclica do Câmera Topográfica (a
   faixa sob o topo é o ciclo inteiro). Os dois lados da feira têm cada um a
   sua matiz — oferta (verde-água, f12) e procura (magenta, f4) — mas a cor
   NUNCA vai sozinha: o selo sempre diz "oferta"/"procura" por extenso.

   A CSP do backend proíbe style="" inline: tudo aqui é classe. */
