+/**
+ * E2E: Compliance Advisor — Clarity Gate (v3 contract)
+ *
+ * Drives the floating advisor widget end-to-end against a stubbed /api/sdk/compliance-advisor/chat
+ * (contract fixtures), so the whole FE chain is exercised without the RAG/LLM backend:
+ *   - underspecified question -> clarify mode (L1 general answer + domain context chips)
+ *   - specific question       -> answer mode (markdown + [n] citation coupling + evidence pane)
+ *   - clarify -> pick a context -> scoped answer
+ * Runs on CI / macmini (needs the Next app on :3002).
