Interactive low-resolution hippocampus WSI density inference for pyramidal cells,
interneurons, and astrocytes using the released CALHippo density model.

Use a bundled LR crop example or upload a LR PNG with an optional ROI GeoJSON.
The demo runs on CPU and returns all-class and per-class density maps, sampled
point maps, and predicted counts.
