"""One live end-to-end check of LLM item generation (ITEM_GENERATION.md).

Calls the real provider (whichever key is configured - Groq or Anthropic),
prints the drafted items, and exits non-zero on failure. Run it once after
setting a key, and again after any provider/model/prompt change:

    cd backend && ../scripts/smoke_test_generation.sh   # or:
    cd backend && GROQ_API_KEY=... .venv/bin/python ../scripts/smoke_test_generation.py
