New "model" family in the gallery: router_gating (mean soft gate weight vs. pre-step energy, showing the router's soft decision boundaries) and router_share_by_pdg/router_share_by_process (stacked top-1 dispatch share by species / true physics process). Needs a live checkpoint's Router, so it's a documented exception to the rest of the package's polars/numpy-only contract; gracefully degrades to a placeholder for non-MoE checkpoints.
