Detailed Description

Self-consistent coupling f = sign * 4piG * (rho - rho0).

CONTRACT: pointwise ELLIPTIC brick, device-callable (POPS_HD), no global state. sign = +1 gravity (standard Poisson), sign = -1 plasma (Gauss sign). rho0 = 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.
