# all distros in parallel inside a single CI job (one runner instead of a
# matrix). Each distro gets its own copy of the checkout so the concurrent
# in-container installs never race on the shared working tree.
#
# Inputs via env:
#   NIX_CONFIG          nix access-tokens block (job env).
#   INFINITO_VENV_DIR   venv path inside the container (from default.env).
#   RUNNER_TEMP         runner scratch dir for the per-distro copies.
#   GITHUB_WORKSPACE    the checkout to install and test.
#
# The distro set comes from INFINITO_DISTROS, which the env layer generates
# from the meta/distros.yml SPOT.
