/*
 * carousel.css — shared carousel + lightbox for theorganist24-web.
 *
 * Ported from the Wardrobe suite's cs- component set. The key design
 * decision is a transform-based slider (translateX) rather than native
 * overflow scroll: the .page wrapper uses backdrop-filter, which creates
 * a stacking/containing context that breaks both position:fixed overlays
 * and reliable overflow scrolling. The slider avoids native scroll
 * entirely, and the lightbox lives OUTSIDE .page (see base.html overlay
 * block) so it can use position:fixed correctly.
 *
 * Namespace: cs- to avoid collisions with area-level styles.
 *
 * Tokens: uses theorganist24's variables (--accent, --cream, --rule,
 * --muted, --space-*) with fallbacks for safety.
