   KOI — el despiece, estilos. Mismo motor que BRASA / QUINTO / ZORTZI
   (js/despiece.js) sobre el fondo oscuro #1A100D: fotograma real (Seedream +
   Kling), velo arriba y abajo, etiquetas numeradas en hueso con línea que
   crece desde un punto rojo. Debajo, el carrusel de piezas (js/carrusel.js):
   el lienzo deja libre esa franja para no tapar el sushi.
