/* ============================================================
   Blog Voltaire Vélos — mesma identidade da loja (Inter, preto/branco,
   cantos suaves), mas leiaute de conteúdo: coluna estreita,
   tipografia maior e respiro entre blocos.

   Vive à parte do index da oferta de propósito: a página de venda
   é longa e frágil, e não vale a pena mexer nela para publicar
   artigo.
