**🚧 PLACEHOLDER VERSION FOR FRONTEND DEVELOPMENT**
This API returns mock detection data so frontend developers can integrate while we optimize ZeroGPU inference.
✅ **What works now:**
- API contract matches final version
- Realistic response structure
- Random detections from your prompt
- Placeholder annotated images
🔜 **Coming soon:**
- Real Grounding DINO + SAM2 inference
- Accurate object detection
- Proper segmentation masks
- GPU-optimized with ZeroGPU
**For Frontend:** Use this to develop the UI/UX. Response structure will remain the same when we enable real ML.
