+identified a viewport transform: 351 x 760 at DPR 0.9 yields a 390 x 844 CSS
+viewport. A fresh-tab attempt at that exact CSS size showed the Overview DOM,
+but its single screenshot attempt still failed with the 5-second CDP timeout.
+The earlier 433 x 938 CSS screenshot is retained as narrow-view evidence only;
