/* ══════════════════════════════════════════════════════════════════
   Blog HeyBira — sistema editorial

   Estrutura, hierarquia e componentes espelham o blog do Sistema
   Elementar (grid de 3 colunas, meta em monoespaçada, régua de
   compartilhamento lateral, faixa de estatísticas, caixa "em resumo",
   acordeão de FAQ, cartão de autor, navegação anterior/próximo).

   A paleta é a do HeyBira, não a do Elementar: creme/laranja no lugar
   de branco/vermelho. Blog e landing page dividem o mesmo domínio —
   trocar de paleta entre uma página e outra leria como site invadido.
