/*
 * Avo6 Outils — styles.
 * 1) Les composants du thème Avo6 Pro (.calc, .field, .btn, .card, .pill, .grid,
 *    .calc-result, .seg, .input-unit) sont réutilisés tels quels.
 * 2) Les règles de repli :where(...) ont une spécificité nulle : le thème garde
 *    toujours la priorité, mais les outils restent utilisables si le thème change.
 * 3) Les couleurs viennent des variables du thème, avec valeurs par défaut.
