Functions
BCRec	pops::detail::derive_aux_bc (const BCRec &b)
	Aux-channel BC derived from the potential phi BC: a periodic BC stays periodic, any other becomes Foextrap (order-0 extrapolation).

template<class Bz >
void	pops::detail::fill_bz_box (Fab2D &f, const Box2D &box, const Geometry &g, const Bz &bz)
	Writes B_z(x, y) at component kAuxBaseComps on box `box` of fab `f`, sampling `bz` at the cell centers of geometry `g`.

Detailed Description

Helpers shared by the three couplers (single-block Coupler, SystemAssembler, AmrSystemCoupler) for the aux channel.

Centralizes two bodies that were duplicated verbatim:

derive_aux_bc: aux-channel BC derived from the phi BC (periodic preserved, everything else -> Foextrap).
fill_bz_box: kernel that writes B_z(x, y) at component kAuxBaseComps on a box of a Fab2D, from a given geometry. PURE extraction: the bodies are taken verbatim (bit-identical). What DIFFERS between couplers (compile-time vs runtime guard, valid vs grown box, per-level geometry, call to fill_ghosts) stays on the caller side; only the common content is here.
