Extensions

Each algorithm lives in cellfish.ext.<tool> and is imported lazily:

import cellfish as cf
cf.ext.milo  # loaded on first access

Optional dependencies belong in pyproject.toml extras and should be imported inside functions, not at module import.

Placeholders below are not migrated yet. Implementations will land as ext/<tool>/_prep.py + _plot.py (or a single _core.py until the folder grows).

milo	Milo differential abundance helpers.
liana	LIANA cell-cell communication helpers.
archr	ArchR project → MuData helpers.
drvi	DRVI latent-space helpers.
scenicplus	SCENIC+ heatmap / genome-viewer helpers.
chrombpnet	ChromBPNet contribution / locus / cCRE helpers.
