## 🚀 Quick Start

### Prerequisites
- Python 3.13+
- Node.js 20+
- Ollama (for embedding — **jina-embeddings-v5-small-retrieval**)
- DeepSeek API key

### 1. Setup Backend
```bash
cd webapp/tipitaka-api
python -m venv .venv
.venv\Scripts\activate   # Windows
pip install -r requirements.txt

# Copy .env.example → .env and fill DEEPSEEK_API_KEY
python -m app.main        # starts on :8000
```

### 2. Setup Frontend
```bash
cd webapp/tipitaka-web
npm install
npm run dev               # starts on :5173
```

### 3. Setup Embedding
```bash
# Download jina-embeddings-v5 GGUF
ollama pull hf.co/second-state/jina-embeddings-v5-text-small-retrieval-GGUF:v5-small-retrieval-Q6_K.gguf
```

### 4. Run Tests
```bash
cd webapp/tipitaka-api
python -m pytest tests/ -v    # 35 tests, all passing
```
