Styled Figure + Multi-format Save

Apply a dartwork style preset and create a figure in two steps — dm.style.use("…") then plt.figure(...) — then finish with the dm.save_formats(fig, name, formats=(...), dpi=...) multi-format save recipe (shown commented at the bottom). Pass any preset name ("scientific", "report", "web", …) to dm.style.use.

The figure also inlines the minimal-axes recipe (hidden top/right spines + a light dashed y-grid), the idiom that replaced the removed spine helpers.

Figure created with dm.style.use + plt.figure.
Figure size: [6.69291339 4.01574803]
