   [hidden] must always win
   ------------------------------------------------------------
   The UA rule `[hidden] { display: none }` has lower specificity
   than ANY class selector. So any component styled with
   `display: grid` / `flex` silently un-hides itself when the
   `hidden` attribute is applied. That is how an empty status box
   and a whole post-submit block leaked onto the page.

   These two selectors restore the expected behaviour globally, so a
   new component can never reintroduce the bug.
