   this rule, the class-based `display` declaration wins over the
   attribute's default `display: none` (a CSS-specificity gotcha), so
   those elements would stay visible at all times regardless of the
   `hidden` attribute actually being set. This single rule makes `hidden`
   always win, everywhere, no matter what other display value a class

   left:) instead of logical ones, where a real visual mirror is wanted.

   mirrored — only navigation/UI chrome and text alignment.
