/*
 * Shared styles for the in-browser WASM demo surfaces (Original preview +
 * A2UI streaming renderer). Used by both the homepage demo (index.html) and
 * the workbench (workbench.html). Anything that styles output produced by
 * docs/js/wasm-demo.js belongs here, not inline on a single page — that's
 * how we keep the two surfaces from drifting.
 *
 * Loaded after design-system.css so it can reference --dp-blue, --border,
 * --text-*, --bg-*, --radius-sm, --font-mono, --font-display, --success,
 * --success-bg, --dp-blue-faded, --dp-blue-border.
