KeyError: 'X_umap'```

Start with the PBMC notebook step calling snap.pl.umap and inspect snapatac2/plotting/init.py around the umap entry point at line 265. Reproduce the KeyError in the recommended container, then trace why the input lacks X_umap; the issue is done when the notebook call runs successfully with the expected embedding.
