+Author: Philip Rogers <pdr@chromium.org>
+Date:   Fri Jul 17 13:12:46 2026 -0700
+
+    Add AutoDarkModeSVGSizeThreshold kill switch flag
+    
+    This patch adds an enabled-by-default feature flag for the code in
+    https://crrev.com/b5934b11cfc2948f8b97ebb0997aab5f77e2fe2c, for the
+    unlikely case that it causes a regression and needs to be disabled.
+    
+    Bug: 449909524
