/* Experiment variants + the lab bar. TEST ONLY — the bar renders solely when
   the lab flag is on, and every experiment's first variant is current
   behaviour, so with the lab off this file changes nothing. */

/* Variants for whatever is currently being tested go here.
   Text size, contrast and layout moved to real preferences in
   theme.css once they stopped being open questions. */
