/* ============================================================
   Kids Kingdom - Worksheet Floating Trigger + Popup
   ONE small corner icon (not a wide banner). Counts down once,
   then becomes a clickable icon with a little sparkle pulse.
   Tapping it opens a compact popup (zooms in from the corner)
   listing every worksheet type available for this page - each
   with its own small "Download" button that opens in a new tab.
   Works the same on mobile and desktop, just sized down further
   on small screens.
