/*
 * Styles des GUIDES (pages éditoriales autonomes, hors bundle React).
 *
 * Feuille séparée de `legal.css` : une page légale se parcourt en diagonale,
 * un guide se lit. D'où une colonne plus étroite (680 px, ~75 signes), une
 * hauteur de ligne plus généreuse, et de quoi poser des tableaux comparatifs,
 * des encadrés et un appel à l'action en fin de lecture.
 *
 * Aucune police distante : la pile système suffit et évite un aller-retour
 * réseau sur une page dont le seul enjeu est d'être lue vite.
