Target fields on the admin hints page. The dashboard shows the four automatic hints after admin hints when their condition is true, using data Core already serves. HintText renders **bold** and safe links (app path or https) as React elements, never HTML, in hints and news. Auto-close without tick hides for this session, X for 7 days, tick + X for good.
