pub trait ProximalVector: Clone + ElemDivAssign<f64> + DotSlice<f64> + SubScalarAssign<f64> + SumEntries<f64> + ScaledSubSlice<f64>

Owned CPU storage for a backend's product vectors.

Matrix products and normalization remain in LazyMatrix. This capability supplies reusable buffers and bridges native vectors to the slice-based predictor and proximal capabilities. It does not represent device storage.

LazyMatrix vectors with VectorOwned<Owned = Self>, mutable indexed access, and the normalization operations below implement this trait automatically. Indexed access may be strided; it does not require contiguous storage.
