 ### Breaking Changes
 - Replace CLI `--geometry` with repeatable `--layout` flags such as `--layout euclidean`, `--layout poincare`, and `--layout spherical`.
-- Replace `Dataset.compute_visualization(geometry=...)` with `Dataset.compute_visualization(layout=...)`; bare `spherical` layouts now resolve to 3D.
