/*
 * Couche de compatibilité Bootstrap 5 -> aspect Bootstrap 3
 *
 * Le site a été migré de Bootstrap 3.3.5 vers Bootstrap 5.3. Ce fichier,
 * chargé après bootstrap.min.css, restaure les valeurs graphiques de
 * Bootstrap 3 (typographie, grille, couleurs et composants) afin que
 * l'aspect du site reste inchangé.
 *
 * Correspondance des points de rupture (BS3 -> BS5) :
 *   xs (< 768px)        -> (aucun) / sm
 *   sm (768px - 991px)  -> md
 *   md (992px - 1199px) -> lg
 *   lg (>= 1200px)      -> xl / xxl
