   INVESTISSEUR AUTODIDACTE — charte graphique
   Thème enfant Avada · fichier : ia-charte.css
   ------------------------------------------------------------
   TOUTES les règles sont préfixées par .ia-page :
   tant que ce préfixe est en place, ce fichier ne peut rien
   casser sur le reste du site. Il ne s'applique qu'aux blocs
   placés dans un conteneur <div class="ia-page"> ... </div>.

   Quand la page est validée et que tu veux étendre la charte
   Ã  tout le site, tu remplaces globalement ".ia-page " par
   "" (chaîne vide) dans ce fichier, et ".ia-page{" par ":root{".
   ------------------------------------------------------------
   Les variables de couleur et de structure sont regroupées
   dans le tout premier bloc : c'est le seul endroit à modifier
   pour changer la charte.
