/* tradeportpilot.com — pages publiques (accueil, acheteurs, fournisseurs).
   La page prend la palette de la section qui passe au milieu de l'écran (attribut data-palette posé sur <html> par
   app.js) : fond et texte glissent d'une palette à l'autre. Des formes décoratives défilent chacune à sa vitesse
   (parallaxe) ; les petites, plus lentes et floues, donnent la profondeur. Rien n'est téléchargé : formes en CSS,
   polices du système. Mouvement réduit respecté. */
