+      url
+    ]);
+    
+    let output = '';
+    
+    proc.stdout.on('data', (data) => {
+      output += data.toString();
+    });
+    
+    proc.on('close', (code) => {
+      if (code === 0) {
+        try {
+          // Extract JSON (last line)
+          const lines = output.trim().split('\n');
+          const json = JSON.parse(lines[lines.length - 1]);
+          resolve(json);
+        } catch (e) {
+          reject(e);
+        }
+      } else {
+        reject(new Error(`Exit code: ${code}`));
+      }

+
+```bash
+node scripts/playwright-stealth.js "https://news.example.com/article/123"
+```
+
+### Scraping E-commerce Products

+
+## Troubleshooting
+
+### Issue: Page Not Fully Loaded
+
+**Solution:** Increase wait time
+```bash
+WAIT_TIME=20000 node scripts/playwright-stealth.js <URL>
+```
+
+### Issue: Still Blocked by Cloudflare
+
+**Solution:** Use headful mode + manual wait
+```bash
+HEADLESS=false \
+WAIT_TIME=30000 \
+node scripts/playwright-stealth.js <URL>
+```
+
+### Issue: Requires Login
+
+**Solution:** Manually login first, export cookies, then load
+(Future feature, currently not supported)
+

+
+## Performance Tips
+
+1. **Parallel scraping:** Use `Promise.all()` or shell `&`
+2. **Delay requests:** `sleep 5` to avoid IP blocking
+3. **Use proxies:** Rotate IPs (future feature)
+4. **Cache results:** Avoid duplicate scraping
