/*
 * Acervo: the catalog below the approved Hero. Loaded last on /conteudos/ only.
 * The Hero (.ea-drift), the episode cards and their hover, the reading-progress line
 * and the rail-progress line keep their own rules (hero.css, library.css,
 * experience.css); this sheet composes everything around them.
 *
 * One family only: the site's sans. No numbering, no slate lines. The series are
 * chosen by their pictures, each chapter opens with its synopsis and clear actions,
 * and the page ends with the complete index.
