	# Per-backend isolation jobs.
	#
	# Each job below installs exactly ONE array backend on top of the base
	# `requirements.txt` (numpy + array_api_compat) and runs the full test
	# suite with that backend set as the saiunit default via the
	# `SAIUNIT_DEFAULT_BACKEND` env var (read in conftest.py).
	#
	# Goal: prove that `pip install saiunit[<backend>]` works end-to-end and
	# that backend-specific kwargs / hidden cross-backend dependencies cannot
	# leak through saiunit's public API.
	#
	# The previous ``test_linux`` / ``test_macos`` / ``test_windows`` "install
	# everything" matrix was removed: ``test_pure_jax`` is the same workload on
	# Linux (saiunit's primary support target), and the per-backend isolation
	# jobs catch the cross-backend bugs the multi-backend matrix could not.
	#
	# cupy is intentionally not included: GitHub free runners have no GPU.
