Detailed Description

template<class Limiter, class Flux, class Model>
struct pops::detail::AdvanceImex< Limiter, Flux, Model >

IMEX advance: per substep, EXPLICIT half-step (source-free transport) + stiff IMPLICIT source.

mask: implicit mask CARRIED BY THE BLOCK (overrides the model default is_implicit), resolved once when the block is added against its variable names/roles. Inactive mask (default) -> backward_euler falls back on model_is_implicit -> advance bit-identical to the historical one.
