   SOCLE — remise à zéro, grille et utilitaires
   --------------------------------------------------------------------------
   Ce fichier remplace Bootstrap. Il reprend exactement les classes utilisées
   par le site (container, row, col-*, g-*, d-*, mb-*, form-*, w-100…), donc
   le HTML n'a pas changé — mais il pèse ~8 Ko au lieu de 232 Ko.

   Bootstrap embarquait des centaines de composants dont le site n'utilisait
   rien (carrousels, accordéons, tableaux, badges, thèmes…) : c'était le plus
   gros frein au chargement des pages.

   Points de rupture (identiques à Bootstrap 5) :
      sm 576px · md 768px · lg 992px · xl 1200px · xxl 1400px
