Detailed Description

Minimal magnetic-field-only state for static field construction.

The B-only path deliberately registers only the magnetic components as conservative/primitive variables. It is intended for static potential (and other field-construction) cases; it does not provide a time-evolving induction equation. The legacy MHD-embedded magnetofriction path is intentionally unaffected by this module.
