 *
 * FICHIER SÉPARÉ DE blog.css, ET C'EST DÉLIBÉRÉ. `blog.css` pèse 72 Ko et il est
 * chargé par /blog ET par la page de profil : toute retouche s'y répercute sur
 * deux écrans sans rapport avec les formations. Les deux espaces sont voisins,
 * ils ne sont pas le même.
 *
 * Il ne définit AUCUNE couleur en dur pour le fond, le texte ou les bordures :
 * tout passe par les variables du design system (public/css/base/_variables.css),
 * redéfinies par mode_clair.css et mode_sombre.css. Le mode sombre fonctionne
 * ainsi sans une seule règle en plus.
