name: Build check

# Proves the split Dockerfile actually builds (repo-split Stage 7b) -- NOT a
# live boot+healthz check. content.register() fetches the IndexNow key from
# backend at import time with no retry (documented Stage 4 behavior,
# unchanged here); without a real, reachable backend this process crashes
# immediately on import, by design -- so a standalone boot check would either
# be fake (skip the real import path) or require checking out and booting
# thermograph-backend too. That's the real fix (a genuine cross-repo
# contract-test job, same pattern the original repo-split plan already
# scoped for the /cell + ETag contract), not yet built -- flagged as a real
# gap, not silently skipped. Full pytest-suite migration is separate,
# deferred follow-up work too, same category as thermograph-copy's deferred
# vendoring.
