   IMAGE PROTECTION
   Lightweight client-side measures to
   discourage right-clicking, dragging, and
   basic long-press downloads on instructor images.
   Note: Nothing on the web fully prevents saving
   (users can still screenshot or inspect), but these
   steps raise the bar for casual downloads.
