/* ==========================================================================
   ACM Lightbox (Theme)

   A “smaller modal window” image viewer with:
   - Close (X)
   - Resolution readout
   - Zoom slider + +/- buttons

   Design note:
   This is like a centered “overlay panel” in a design tool, not a full-screen takeover.
