Detailed Description

template<class Limiter, class Flux, class Model, class Stepper = SSPRK2Step>
struct pops::detail::AdvanceExplicit< Limiter, Flux, Model, Stepper >

EXPLICIT advance: n substeps of the Stepper stepper (SSPRK2 by default, SSPRK3 optional) on the transport+source residual.

The RK scheme is a template parameter (NAMED FUNCTOR from the core: SSPRK2Step / SSPRK3Step) -> same device-clean contract as SSPRK2Step. SSPRK2 reproduces the historical advance exactly (bit-identical).
