Pipeline

Low-res fields (2D winds + advection) → upsample classes to full res.

Performance: all physics on compute grid only; 4 seasons; 3 advection iterations per season; no per-cell objects.
New realism: 2D wind field + semi-Lagrangian moisture advection + convergence + orographic uplift/rain shadow.
