/* ==========================================================================
   One event's own look (written by hand; marketing can't do this in the designer).
   main.js labels the page with the event shown: <html data-event="fall-gala-2027">.
   Start every rule with that label so it touches only that event, put pictures in
   public/images/, check it at /?src=fall-gala-2027 (the designer's preview doesn't
   show it), then push. Delete the rules once the event is over. Example:

   html[data-event="fall-gala-2027"] .top { background: url(images/leaves.jpg) center / cover; }
   html[data-event="fall-gala-2027"] body { font-family: Georgia, serif; }

   Event labels are lowercase. Fields can't be added or removed this way, only restyled.
