rkolleradded before and after screenshots to illustrate the change. the MR is fixing the problem in the short term thanks for that. but in regard of readability that card heading is really hard to process. It would be good if issue around #2860419: [Meta] Appearance page is too long and confusing could get moving again. one of its child issues would for example move the experimental label from the heading to chips #3249374: Redesign the cards for the Appearance page

longwaveCommitted and pushed to main. I assumed admin theme would land in 11.x as well but it's not there, waiting for clarification from @lauriiii on that.
