+Deployment Visual Verification
+==============================
+
+Post-deployment step that uses vision to verify UI is rendered correctly.
+Takes screenshots of deployed endpoints and checks for:
+- Page rendering errors
+- Missing assets
+- Layout breaks
+- Error messages visible
+- Expected content present
+
+Usage:
+    python scripts/deploy_verify.py check https://my-app.com
+    python scripts/deploy_verify.py check https://my-app.com --expect "Welcome"
+    python scripts/deploy_verify.py batch urls.txt
