   Galaad — carousel.css
   Carrousel 3D de 7 boucliers narratifs.
   - Front face : illustration avec bordure ink propre tout autour.
   - Back face : porte en bois DIRECTE (arche, 2 battants, poignées).
     Clip-path inversé (arche) + rotateX(180°) pre-rotation →
     quand le flipper rotateX(180°), la porte apparaît bien en
     forme d'arche (pointe en haut) avec texture bois immédiate.
