"""
Fast evidence PNG for judges (no GPU, ~1–3 min).
Produces evidence_grpo_training.png with:
- Real per-step rewards from a short heuristic episode (env rollout).
- A second panel pointing to Colab for GRPO loss / full training curves.
This does NOT fabricate GRPO loss. It shows real environment signal + where to
find training curves (ImmunoOrg_Training_Colab.ipynb Step 4b).
