 ## 7. Next.js API Proxy Routes
 
-- [ ] 7.1 Create `src/app/api/predict/route.ts` — POST proxy to `${INFERENCE_API_URL}/predict` with timeout handling
-- [ ] 7.2 Create `src/app/api/predict/batch/route.ts` — POST proxy to `${INFERENCE_API_URL}/predict/batch` with INFERENCE_BATCH_TIMEOUT
-- [ ] 7.3 Create `src/app/api/model/info/route.ts` — GET proxy to `${INFERENCE_API_URL}/model/info`
-- [ ] 7.4 Add environment variables to `.env.local`: INFERENCE_API_URL, INFERENCE_API_TIMEOUT, INFERENCE_BATCH_TIMEOUT, NEXT_PUBLIC_PREDICTIONS_ENABLED
