/* === CARDS — SAFETY NET stacking ============================================
   Garantit que le badge ✓ d'une option sélectionnée passe TOUJOURS au-dessus
   d'une éventuelle illustration .card__mockup, même si une page redéfinit
   localement .card__check / .card__mockup sans z-index.

   Contexte : sur etape-7, les cartes "style de montage" ont une illustration
   SVG (.card__mockup) déclarée APRÈS .card__check dans le DOM. Sans z-index
   explicite, l'ordre source l'emporte → le mockup masque le ✓ blanc et il ne
   reste qu'un demi-cercle vert tronqué en haut à droite.

   Régression : observée puis corrigée 2026-05-15. Ces deux règles globales
   évitent le retour du bug même si la copie inline d'une page est altérée
   par un linter / refacto. NE PAS RETIRER.
