/**
 * Image Galaxy widget.
 *
 * A scroll-driven 3D field of floating images behind an animated heading and
 * pill button. Motion is applied per-particle by assets/js/widgets/image-galaxy.js;
 * this file owns layout, the depth wash, the heading word-reveal and the button.
 * All selectors are scoped under .rsi-galaxy so multiple instances and other
 * page styles never collide.
 *
 * Ported from Skyweb Toolkit; theme-variable fallbacks replaced with literals
 * (RSI runs Woodmart, which has no --skyweb-* tokens), heading set to Alexandria.
