Multimodal agent experiment workflow figure

Create a polished research workflow figure for a multimodal agent evaluation experiment. Landscape academic diagram on white background. Show stages Dataset Curation, Prompt Design, Tool Sandbox, Model Runs, Judge Ensemble, Error Taxonomy, Human Audit, and Final Report. Use a restrained blue, slate, and orange palette, vector-clean boxes, thin arrows, numbered callouts, tiny legends, and paper-ready typography. It should look like Figure 1 from a strong systems paper rather than a marketing poster.
