Function dispatch_chunked_mixed_dot_product 

pub fn dispatch_chunked_mixed_dot_product<A: Algebra<F> + Dup, F: Dup, const N: usize>(
    values: &[A; N],
    coeffs: &[F; N],
    chunk: usize,
) -> A

Lower a runtime chunk size into a const-generic call to the fixed-chunk dot product.

Each backend picks its preferred chunk size at runtime; the inner routine needs it as a const for unrolling. This wrapper bridges the gap.

Supported sizes: 1, 2, 4, 8, 16, 32, 64 — powers of two only, so the inner balanced tree stays balanced.

Panics

Runtime panic if chunk is outside the supported set.
