/**
 * \brief Apply EB state redistribution to a temporary tendency field.
 * \tparam EBFactType EB factory interface type, either AMReX native or ERF auxiliary.
 * \param ncomp Number of components to redistribute.
 * \param geom Geometry associated with the result field.
 * \param result Output redistributed field.
 * \param result_tmp Input temporary field before redistribution.
 * \param state State field used by redistribution slopes.
 * \param ebfact EB factory supplying flags and geometric moments.
 * \param bc Boundary conditions for the state components.
 * \param dt Time-step size used by the redistribution operator.
 * \param igrid Optional ERF integer-variable index for staggered grids; -1 means cell-centered.
