Detailed Description

Single-box MultiFab AMR stack: struct detail::AmrLevelMF and the recursive engine (amr_step_2level_mf, subcycle_level_mf, amr_step_multilevel_mf).

TEST ORACLE, out of production.

Layer: include/pops/numerics/time. Role: original SINGLE-BOX AMR engine, kept in detail:: as a validation oracle. Intermediate link of the Fab2D (amr_reflux.hpp) -> MF (here) -> MP (amr_subcycling.hpp) parity chain, which proves the multi-patch engine bit-identical to the single-box one up to N levels (which the Fab2D 2-level/1-comp/Rusanov-only test does not cover). Contract: one conservative step with Berger-Oliger subcycling (ratio 2, dt/2 per substep) with reflux at each coarse-fine interface; periodic BCs at level 0.

Invariants:

no longer called in production (AmrCoupler goes through advance_amr);
parity guards: test_amr_reflux_mf (vs Fab2D), test_amr_multilevel_mf, test_amr_multilevel_multipatch guard 1 (MP vs MF, max|dUc| == 0);
aux held elsewhere (pointer); rC* = region (coords of THIS level) refined by the child, valid only if has_fine.
