 written under `var/custom_yolo_runs` and are scanned by the results dashboard.
 When a dataset is selected, the dataset panel shows its custom YOLO `best.pt`,

+prediction previews, heatmap previews, and inline training curve previews.
 Segmentation previews, YOLO heatmaps, and loss/metric artifacts are grouped on
 the results dashboard, and YOLO-style `results.csv` files are parsed into
 lightweight training curves.
