# harness that runs against a different tree from the one that ships is
# testing something nobody deploys (improvise-vvl3).
#
# Re-run THIS script, never `web/assemble.sh harness/serve` alone: assembling
# starts with `rm -rf` of its output, which deletes opfs/ and the fixtures
# (improvise-mkbp). opfs.spec.js says so if it finds opfs/ missing.

# worker.js answers it with an empty model -- so every spec over these asserts
# real labels rather than that a grid exists.
