 * ATTPS Renov Sim — simulateur (front). Repris de la maquette validée (univerture2026/.claude/etude-simulateur-thermique/

 * pastille de sélection, choix en pilules, champs en pilule, pastilles d'étapes).
 *
 * Pas de système de thèmes pour le moment (C3) : les jetons --atrs-* prennent directement les couleurs et polices du

 * plus tard redéfinir ces seuls jetons.
