Function yolo26 

pub fn yolo26<D: Float + Send + Sync + 'static>(
    nc: usize,
    variant: &Yolo26Variant,
    head: DetectHead,
) -> impl Fn(SymTensor) -> DetectOutput

YOLO26 single-head forward closure (inference or one-head training).

Arguments

• nc — number of detection classes (e.g. 80 for COCO)
• variant — model size variant (N / S / M / L / XL)
• head — OneToMany (cv2/cv3, dense) or OneToOne (one2one_cv2/cv3, inference)

For dual-assignment training use yolo26_dual instead.
