"""Render the four-scenario Pareto-front panel (Fig. 3).

Reproduces ``paper/figures/fig_pareto_fronts.png`` from the committed
evaluator-truth Pareto fronts under ``reports/pareto_fronts/`` (regenerate
those first with ``make pareto-fronts``). The plotting logic itself lives in
:func:`roverdevkit.tradespace.visualize.plot_pareto_fronts`. Part of the
``make figures`` manuscript-figure pipeline.
