   Alvance — páginas editoriais: índice do blog e artigo.

   Carrega sempre depois de style.css e só acrescenta: os tokens, o cabeçalho,
   o rodapé e os botões continuam vindo de lá.

   O HTML destas páginas é gerado pelo servidor (server/src/render.js). Mexer
   numa classe daqui pede uma olhada lá.
