   First paint
   The workflow routing runs in R, so for a moment on load the browser showed the validation tabs
   and start page before they were hidden again. A cover sits over the page until the routing has
   run. Deliberately NOT done by hiding the individual tabs in CSS: the routing reveals them with
   jQuery .show() on the parent <li>, which would not override a rule on the <a> inside, and a
   validation build would then have permanently invisible tabs.
