Detailed Description

Mesh and domain shared by all blocks (physical parameters are per block, in the ModelSpec).

GEOMETRY ("polar grid" work, Phase 1): the CHOICE of geometry lives HERE, in the mesh config, NOT in the scheme (FiniteVolume stays reconstruction + Riemann + variables). Default "cartesian": square domain [0,L]^2, behavior and numerics STRICTLY UNCHANGED (bit-identical). "polar" describes a global ring r in [r_min, r_max] x theta in [0, 2pi) (cf. PolarGeometry); it is carried by pops.PolarMesh on the Python side and is NOT yet wired into System::step (Phase 1 ships the geometry + the polar transport operator + its MMS validation; polar transport through System, which would also require the polar Poisson, is a later phase). Polar fields are ignored while geometry == "cartesian".
