"""Budget-forcing chart for the model card: overall accuracy vs thinking budget at 2 loops, for base Dory,
Dory-Beam-4B (default effort) and Dory-Beam-4B-Accurate.

  python3 scripts/make_budget_chart.py   # -> release/model/assets/accuracy_vs_budget.png

At each budget, a sample still thinking is closed with "\n</think>" and gets up to 1,024 answer tokens
(modal_app/eval_dory.py::budget_force). The last point is the uncapped 64k run. Same emphasis form and colors as
scripts/make_chart.py: base in the de-emphasis gray, the two Dory-Beam models in categorical slots 1 and 2.
