test_refinement_mrt_gpu, test_shifted_jets_gpu and
test_refinement_blocked_base pass refinements/level_* lists. The three
blocked-base rejection cases keep their inputs per level; base-only
blocks now meet the level-list rule (blocked refined levels below) where
the legacy keyword check fired before. Assertions unchanged.
