/* =====================================================================
   ui2, familia d-item: CHANGELOG COMPLETO do item (item/<slug>/changelog/)
   ---------------------------------------------------------------------
   Estrutura da pagina de changelog do gpltimes, pele do ui2: faixa com
   migalha e pilulas, abas de filtro com contagem, linha do tempo por ano
   (um cartao por versao, as 3 mais novas abertas) e coluna lateral fixa
   com o item e o resumo do que mudou. No celular a lateral se desmonta
   (display:contents): o cartao do item sobe para antes da linha do tempo e
   o "O que mudou" desce para o fim, sem duplicar markup.
   So tokens: nenhuma cor, fonte, raio ou sombra literal.
