   Platform floating badge (opt-out)
   The badge is injected server-side just before </body> and carries
   `display:flex` in its own <style>.  `!important` on an author
   rule beats a non-important rule regardless of source order,
   so this hides it.  The second line also covers the class form
   and blocks pointer events in case the platform changes the id.
