/**
 * Gallery mode of the IBIA lightbox (assets/js/ibia-lightbox.js), 16 Oct 2026.
 *
 * The base overlay, pane and close button are in ibia.css, built for the
 * organigram. Photos differ: they fit the screen whole rather than scrolling,
 * sit on the dark backdrop without the chart's white card, and a gallery adds
 * Previous / Next and a counter. Everything here is scoped to
 * .ibia-lightbox--gallery, so the organigram is unchanged.
