Detailed Description

Neutralizing background f = alpha (n - n0).

Models a fixed neutralization background of density n0.

CONTRACT: pointwise ELLIPTIC brick, device-callable (POPS_HD), no global state. Reads only the density. alpha = effective charge of the background; n0 = density of the neutral background.

ROLE-AWARE (audit sec.5): c_rho member, default = component 0, resolved by model_factory via the Density role of the transport. Canonical == default -> bit-identical. See ChargeDensity.
