/* ============================================================
   BIX · Página do blog (carregada só em blog.html)

   Reaproveita o que já existe no sistema das internas: a busca
   (.fq-search) e o contador (.fq-count) são os mesmos da FAQ, os
   botões e o CTA final também. O que é novo aqui: a barra de tags,
   a grade de artigos e o estado vazio.
