     views/BEngine/N/upload-photo-hotel.php  (Photos Hotel)

   New class prefix (.pr-*) rather than edits to manager-img.css, which is
   still loaded and owns .item-search, .box-item-search and .main_img.

   Lives here, not beside manager-img.css, because .gitignore excludes
   public/BEngine/lib/ — a new file there never reaches production.
