/* Placeholder. phpBB3 looks up theme/{LANG}/stylesheet.css per user
   language; if no style in the chain defines one for `hr_x_vi`, the
   browser gets a 404 (nginx returns the HTML error page → strict-MIME
   warning in the console). This empty file silences that without
   committing to any styling.

   en/stylesheet.css upstream contains exactly one rule:
       .online { background-image: url("./icon_user_online.gif"); }
   (the green "user online" indicator). If we ever want that on the
   Croatian locales, drop the same rule here and copy the .gif beside
   this file. */
