"""Live smoke test against the real LiteLLM proxy.

NISSE_LLM_BASE_URL alone decides whether this runs: if it is set, the live
path is expected to work, and anything else missing is a *failure*, not a
skip. A half-configured environment must not pass quietly as a skip — that is
how a broken CI credential hides.
