   Store Backup - site vitrine v2.
   Meme grammaire visuelle que BCProductInStock (patterns, motion, une seule
   police variable), mais une identite PROPRE a Store Backup, accordee a
   BigCommerce : murs bleu marine, papiers gris-bleu, accent bleu #3C64F4 (le
   bleu du design system BigCommerce). Police : Inter, declinee par taille
   optique (opsz) — sobre et professionnelle. Toute l'illustration est en CSS (frises
   code-barres, pointilles de ticket, etiquettes suspendues) : aucune image
   decorative, seulement de vraies captures de l'app.
   Les noms de variables restent neutres (--deep, --accent) : la palette est
   commune aux deux produits, la metaphore de chacun reste la sienne.
