/*
 * Simulateur de situations professionnelles — feuille de style.
 *
 * CSS natif, sans bibliothèque ni ressource externe : polices du système uniquement.
 * Identité reprise du support de l'atelier : papier clair, bleu nuit, accent argile,
 * et une ligne fine qui sépare deux colonnes (conversation | repères).
 *
 * Trois conventions visuelles portent une information et ne sont pas décoratives :
 *   - hachures            = contenu simulé (mode démonstration) ;
 *   - bordure en tirets   = règle fictive de l'exercice ;
 *   - trait plein / tirets / pointillés = les trois types d'observation
 *     (action de l'apprenant / notion sollicitée par l'interlocuteur / rapprochement à confirmer),
 *     de sorte que la couleur ne soit jamais le seul signal.
