/*
 * ZHS Ecom deck slide player.
 *
 * A framed slide image with a connected control bar underneath: previous,
 * current/total, next. Desktop and mobile use the same artwork and chrome.
 *
 * Tokens come from public/assets/zhs-design-system.css when the host page links
 * it. Every value below carries the canonical fallback, so the player still looks
 * right on a page that has not linked the system.
 *
 * See docs/landing-page-design-system.md and docs/dsl-player-integration.md.
