   MES EXPERTISES - SHOWROOM CREATIF (home), refonte v3
   Trois scenes radicalement differentes (plan technique, bureau en
   flat lay, table lumineuse). Le chrome Pixora (pixel font, volt)
   n'habille que les commandes/legendes ; les pieces exposees gardent
   le registre du client (Bodoni Moda / Archivo), definis ici en
   variables locales (n'existent pas ailleurs dans le theme).
   Voir showroom-v3-spike/NOTES.md (racine du projet) pour le detail
