/*
 * Articles (Les Carnets) : gabarit de lecture partagé par toutes les pages articles/<slug>.
 * Fond papier, tout en Satoshi, une seule échelle de lecture (celle de la documentation) :
 * h2 34 px, chapô 21 px, texte 18 px / 1.7, titres de cartes 21 px / 800, texte de carte 17 px,
 * tableaux 16 px, citation 30 px, libellés 12-13 px. Titre d'article au gabarit d'une page de lecture
 * (36 à 52 px), pas celui des pages vitrine.
 * Encadrés teintés (pas de barre latérale colorée), tableau, étapes, matrice, citation, sources,
 * FAQ et suites de lecture.
 * Les classes ar-* reprennent celles de la maquette modele-article.
