/* ============================================================
   PORTRAIT 3 — PARCOURS
   Une presentation courte et la photo, puis ce qui a fait la personne :
   ses etapes sur une ligne de temps fine, horizontale en desktop,
   verticale en mobile. Sans etape, la section s'arrete sobrement sur ses
   formations — ou sur sa presentation, sans frise vide.

   Signature : la ligne se dessine au defilement et chaque etape s'allume a
   son passage. Sans JS (et a l'export), la ligne est dessinee et toutes les
   etapes sont allumees.
