   HERO -> PROJECT RESUME -> MEDIA -> ROLES -> FULL CASE STUDY

   A pagina e uma sequencia de GRANDES BLOCOS EDITORIAIS (secao 2). Todos os
   blocos — Resume, Media, Roles e cada capitulo — usam a mesma casca:
   .case-block. Mesma largura, borda, padding e distancia titulo/conteudo.
   E isso que faz o capitulo seguinte parecer "o proximo capitulo", e nao
   "outra pagina".

   A v1 congelada usa css/v1/case.css. Nada aqui a afeta.
