/* =========================================================================
   DOME GALLERY : vanilla JS port (no React, no build step)
   Ported from https://reactbits.dev/components/dome-gallery, same visuals
   and drag/enlarge behavior, reimplemented with plain pointer events and
   DOM APIs so it drops into this static site with no new dependencies.
