-## 🔮 Future Features
+## 🗺️ v1.5 Roadmap
+
+- [ ] Show retrieved context (collapsible view of chunks used per answer)
+- [ ] Source citation (display which data source answered the query)
+- [ ] Token cost per query (exact usage and estimated cost under each answer)
+- [ ] Pipeline timing (response generation time displayed)
+- [ ] Route badge color-coding (green/blue/purple/gray for pdf/csv/both/none)
+- [ ] Markdown rendering (properly formatted lists, tables, bold text)
+- [ ] Copy answer button (clipboard copy on each response)
+- [ ] Welcome + example chips (clickable sample questions on empty chat)
+- [ ] Feedback thumbs (±1 per answer, logged for future evaluation)
+- [ ] Dark mode toggle (OS preference detection + manual toggle)
+
+## 🚀 v2.0 Roadmap
+
+- [ ] FastAPI backend (`POST /ask`, `GET /budget`, `GET /health`)
+- [ ] Streaming generator (DeepSeek `stream=True` → `StreamingResponse`)
+- [ ] Conversation history (generator-only, router stays single-query)
+- [ ] Dockerize backend (`Dockerfile` + `docker-compose.yml`)
+- [ ] Svelte chat UI with Vercel AI SDK (replaces Gradio)
+- [ ] Strip Gradio (`app.py`, `gradio` from requirements)
