# #region Test.LLMAnalysisService [C:3] [TYPE Module] [SEMANTICS test, llm, analysis, screenshot, openai]
# @BRIEF Verify LLMAnalysis components — ScreenshotService helpers, LLMClient wiring, image optimization, dedup.
# @RELATION BINDS_TO -> [LLMAnalysisService]
# @TEST_EDGE: login_page_detection -> Markers identified correctly
# @TEST_EDGE: redirect_authenticated -> Non-login redirects treated as success
# @TEST_EDGE: image_conversion -> PNG→JPEG conversion preserves content
# @TEST_EDGE: api_key_bearer_stripped -> Bearer prefix removed from api_key
# @TEST_EDGE: json_supports_free_models -> :free models disable json mode
