/* The `hidden` attribute and author-stylesheet rules like `.btn {

   win ties against the browser's built-in `[hidden] { display: none }`
   rule, so any hidden element with its own `display` rule (buttons,
   flex/grid containers) silently ignores `hidden` and stays visible.
   This forces `hidden` to always win, regardless of what else targets
