   LUMARIO Blog — folha propria do blog.
   Carrega DEPOIS de /forum/forum.css e reaproveita os tokens, a nav, os botoes,
   o avatar, o rail e o rodape de la. Aqui ficam so os componentes que o forum
   nao tem: capa de post, grade do indice e a tipografia de artigo (.prose).

   Vale pro indice (/blog) E pras paginas de post (/blog/<slug>) — uma folha so,
   pra capa e artigo nunca divergirem de cor, raio ou espacamento.
