/* Core Navigation's top bar (`.top-bar`) only shows itself when its
   tools/context/actions regions are non-empty -- but with no blocks placed
   there, the regions still contain whitespace text nodes from the Twig
   loop scaffolding, which defeats the `:not(:empty)` check. Result: an
   empty top bar renders anyway, with the page content pushed down to make
   room for it. We only use the Gin sidebar (the left icon rail), so force
   the phantom bar off and collapse the space it would otherwise reserve. */
