"""E2E test configuration.

These tests are SKIPPED by default. To run them set ``LLM_API_KEY`` and
``LLM_PROVIDER`` (and any model overrides) in the environment, then run:

    pytest tests/e2e -m e2e

They exercise the full OntoCast workflow end-to-end — LLM calls included —
and so they cost real money. Keep them out of CI default runs.
