   Parti pris structurel, à ne PAS reprendre des sites 01/02/03 :
     - en-tête "bon de commande" : ligne d'article tarifée, pas de photo de héros
     - catalogue en tuiles numérotées M1..M7 avec case à cocher décorative
     - frise horizontale (avant / pendant / après) au lieu d'étapes verticales
     - accordéons groupés par thème, pas de liste plate
     - pas de rail sommaire (site 03), pas d'onglets (site 03), pas de colonne sticky (site 02) */
