	# Install build deps into the runtime env and build without isolation, so
	# the editable on-import rebuild (editable.rebuild=true) can find pybind11.

	# Unit + synthetic + real-world (offline, against committed fixtures + DB).
	# The committed mmseqs indexes are version-tagged; if CI's mmseqs differs,
	# arda transparently rebuilds a private cache — this also exercises that path.
