+### 📜 Architecture Evolution
+
+- **v0.1 (The FastAPI Initiation)**: The initial dual-track setup. FastAPI handled data routing, while Gradio rendered the UI. Due to cross-space CORS restrictions and a lack of `x-ip-token` handling, the frontend fell into the ZeroGPU anonymous pool.
+- **v0.2 (The Gradio-Injection Era)**: A modular reconstruction (`core/`, `frontend/`, `ui/`). Introduced the `task_runner` for precise background scheduling and logging. To retain ZeroGPU billing, we hid Gradio components and injected native HTML/CSS/JS via Python. This successfully kept the GPU quota but introduced frontend performance bottlenecks and UI state sync issues.
+- **v0.3 (The Decoupled Proxy UI)**: The ultimate refactor. A 100% native static web UI is decoupled from the FastAPI backend. We implemented a dummy Gradio probe to trick the ZeroGPU scanner and used `ContextVar` to perfectly pass through the `x-ip-token`. Featuring a dual-Space sync mechanism (`frontend_cache`), it delivers zero-latency loading, 100% accurate billing, and a blazing-fast pure native frontend experience.
