/**
 * 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.
 *
 * ---------------------------------------------------------------------------
 * CASCADE ISOLATION (v1.0.1)
 * ---------------------------------------------------------------------------
 * v1.0.0 scoped every selector with a single class (e.g. `.dss-au__drop`),
 * which is (0,1,0) specificity. Any host rule that pairs a class with an
 * element type — `.form-row label`, `.woocommerce ul`, `form.cart span` —
 * all extremely common in WooCommerce themes and cart / product-add-on
 * plugins — is (0,1,1) and wins outright, regardless of load order. That is
 * what breaks the layout: `display: flex` loses to the theme's own
 * `label { display: ...; }`, the flex column collapses to normal inline
 * flow, `gap` stops doing anything because there is no flex context left to
 * apply it in, and the drop zone's children run together exactly like
 * ordinary wrapped text.
 *
 * Two independent layers fix this so the component renders correctly no
 * matter what the host page does:
 *
 *   1. `all: revert` on the specific HTML tags this component creates
 *      (label, span, ul, li, p, button, img) strips away any author-origin
 *      declaration the theme/plugins placed on them, giving each one a
 *      clean browser-default baseline to build on. Deliberately NOT a
 *      universal `.dss-au *` selector: the icons below are inline SVG
 *      coloured via `fill`/`stroke` PRESENTATION ATTRIBUTES, and those sit
 *      at the very bottom of the author-origin cascade — `all: revert`
 *      would strip them too, turning "currentColor" back into the SVG
 *      user-agent default (fill: black, stroke: none) and breaking the
 *      icons. Naming the tags explicitly leaves svg/path/circle/rect/text
 *      untouched, so their colour attributes are safe.
 *   2. Every component selector below is written as `.dss-au .dss-au__x`
 *      (two classes -> (0,2,0)) instead of a bare `.dss-au__x` ((0,1,0)), so
 *      it structurally outranks the class+element-type pattern above. The
 *      properties that are 100% load-bearing for the layout — `display`,
 *      `flex-direction`, `align-items` on every flex container — also carry
 *      `!important` as a last line of defence against a theme rule that is
 *      itself `!important`.
