   Detroit Altar Desktop Hero — Canvas Image-Sequence (desktop-only)

   Replica la técnica validada del mobile pero para viewport
   horizontal (1920x1274). Solo se aplica cuando viewport >= 768px.

   Toda clase usa prefijo "dad-" (Detroit Altar Desktop) para
   evitar colisiones con dam-* (mobile) y .hero-* (v25 desktop).
