/*

        ATTENTION - le design du site ne peut pas être passé en doctype html (html 5) dans la révision 1 du design.
                    bien qu'une révision 2 sera instanciée plus tard, il faudra se contenter de nombreux workaround en restant en HTML TRANSITIONAL 4.01

         Du fait du nombre massif des éléments DE CETTE PAGE (et de ce qui en découlerait) qui seront à revoir pour transformer le design en design responsive et lui appliquer une nouvelle charte graphique..
         .. il est alors plus judicieux de globaliser un TAG unique pour cette tâche pour ne pas alourdir de commentaires le code déjà suffisemment alourdi comme cela!
         
         En gros, ici, pour cette méga-tâche, je vais ré-utiliser le même format maison de commentaires que la tâche [SI-LINDER-PARTNER-2][OSC] pour cette tâche précise:
         --> pour en comprendre les méandres, voir le fichier /[!] - Saphyra-Interactive-TaskList-Explanations/[SI-LINDER-PARTNER-2][OSC]--semantic.php
         ---> mais à la place de [SI-LINDER-PARTNER-2][OSC], ici, on abordera le fichier et sa logique comme faisant parties de la tâche [VTAB-TEAM-LINDER-PARTNER-1][OSC]
