Classes
class	peclet::amr::DistributedFlowMultigrid< Dim, Bits >
class	peclet::amr::DistributedStage< Dim, Bits >
	A SIBLING-MERGE or REPARTITION stage (docs/amr_mg_depth.md §5.6, WO4b; docs/amr_mg_core_boundary.md §5): the moved level lands on a decomposition of its own grid on FEWER ranks — agglomerated(d) for a sibling merge, a fresh proportional ORB on the first np_L ranks for a repartition, both chosen by core's chooseStageTarget — and the ladder continues there as a DistributedFlowMultigrid on the stage's sub-communicator, with its own lockstep lifts, its own halos and, where it blocks again, its own stage.

Functions
void	peclet::amr::removeMeanFvDist (const FvOp &op, View< double > u, MPI_Comm comm)
	removeMeanFv with the two mean sums folded across ranks (identical kernels; the Allreduce sits between the reduce and the subtract).
