+/// End-to-end tests that hit real LLM provider APIs.

+/// These tests are skipped when the required environment variable is absent,
+/// making them safe to compile and run in any environment while still providing
+/// full coverage in CI when secrets are available.
+///
+/// Required env vars (at least one):
+///   ANTHROPIC_API_KEY — runs Anthropic provider tests
+///   OPENAI_API_KEY    — runs OpenAI provider tests

+/// Run manually:
