is there a bug you could link to here so authors can remove this code when it's
done (or otherwise track progress)?

At this point it looks like this perhaps shall be the M-38 finch trial
instead... but bug has been linkified.

+function setupSSLFinchTrial() {
+  if (loadTimeData.getString('trialCondition') == 'V2Yellow')
+    $('body').classList.add('yellow');
+  else if (loadTimeData.getString('trialCondition') == 'V2WithGuard')
+    $('body').classList.add('ssl-guard');
+}
