/* ============================================================
   Sites Station · blog.css: o blog público (a seção da página inicial, a lista e o post).
   Desde a spec 153 as páginas saem prontas do servidor: a capa é uma <img>
   com texto alternativo (e não um fundo), os filtros são links, e o
   cabeçalho é o mesmo do resto do site.
