/**
 * DSS Artwork Upload — front-end styles.

 * Everything is scoped under `.dss-au`, so nothing here can leak into the
 * theme, WooCommerce, or any other plugin. Colours are sampled directly from
 * the DSS logo / "Add to cart" button (#FFD623) and the site ink (#1A1A1A).
 *
 * Mobile-first. The only breakpoint widens the preview card at 480px.
