   --------------------------------------------------------------------------
   Cada banda es una imagen real (composición, curvatura, profundidad,
   textura e iluminación). El CSS solo asegura continuidad de bordes,
   posición y adaptación responsive: nunca dibuja la forma.

   Los assets se entregan YA en la proporción de su banda, por eso se pintan
   con background-size 100% 100% y no con cover. Con cover el recorte
   vertical se comería el borde aplanado del archivo y el seam reaparecería;
   la altura de la banda varía con el viewport, así que ninguna proporción
   fija sobreviviría a un recorte. Sobre curvas abstractas el ajuste
   vertical es imperceptible y mantiene la coincidencia cromática exacta.

   Los velos ::before/::after son cortos (14-18px) y sólo cubren el residuo
   de la compresión con pérdida en la fila del borde (max 7/255 medido).
   No son un difuminado: la imagen sigue siendo la protagonista.

   revela su detalle desde sí misma: la grilla que antes repetía esta
   información abajo desapareció.

   En escritorio el panel se superpone (absolute) en lugar de empujar: así
   la altura del bloque nunca cambia, los filamentos siguen alineados y el
   scroll no da saltos. En móvil sí expande en flujo, con grid-template-rows,
   que es el gesto natural al tocar.

   Los filamentos viven en un SVG de franja izquierda con
   preserveAspectRatio="none": se estiran exactamente hasta donde llega la
   columna de tarjetas, sin depender de una altura fija.
