+
+/**
+ * SECURITY CHECKLIST:
+ *
+ * 1. ✅ NEVER send OPENAI_API_KEY to browser
+ * 2. ✅ Use ephemeral/session tokens with expiration
+ * 3. ✅ Implement rate limiting per user/session
+ * 4. ✅ Authenticate users before generating tokens
+ * 5. ✅ Store session tokens in secure storage (Redis/KV)
+ * 6. ✅ Log all voice session creation for monitoring
+ * 7. ✅ Set maximum session duration (e.g., 1 hour)
+ * 8. ✅ Implement cost controls and usage tracking
+ *
+ * RECOMMENDED ARCHITECTURE:
+ *
+ * Browser Client → Next.js Proxy → OpenAI API
+ *     ↓
+ * Session Token (never sees main API key)
+ *
+ * Alternative: Use OpenAI's official ephemeral key endpoint when available
