/* ===========================================================================
 * Artwork cards + modal carousel
 * ===========================================================================
 * Namespaced `aw-` throughout and kept in its own file rather than folded into
 * does-cloud-compute.css, for the same reason the editor keeps slot prefixes
 * apart: this is going on more than one exhibition page, and the artwork grid
 * must not inherit or fight the artists grid's rules when they sit next to
 * each other on the same page.
 *
 * Visual language is borrowed from does-cloud-compute.css deliberately —
 * 1px/2px white rules, 4px radius, IBM Plex Mono, --rule/--muted/--ink — so it
 * reads as the same page. It does NOT borrow from past-events.css, which is a
 * different page with a different design language.
 *
 * The modal is its own component, not .pc-lightbox. .pc-lightbox is a
 * page-level browser for loose gallery images; this is a per-artwork carousel
 * with thumbnail navigation. They coexist on the DCCeP page — hence the
 * separate z-index band and the separate class tree.
 * =========================================================================== */
