/**
 * `<preview-ui>` — Live code + render in one frame, from a single source. Wrap any authored AdiaUI markup: the same HTML renders LIVE in a stage and appears beside (or below) it as escaped, syntax-highlighted, copyable source via a nested <code-ui>. The code can never drift from the render — it IS the render's source. Batteries-included + HTML-first by construction: write one block of HTML, no inline styles, no JS wiring, and both panes appear. Use it for every component/recipe example so the primary snippet is always real, copyable HTML shown next to the working component.
 *
 * @see https://ui-kit.exe.xyz/site/components/preview
 *
 * Type declarations generated by scripts/build/dts-codegen.mjs from
 * the component's `.a2ui.json` sidecar(s). Edit the source `.yaml`,
 * run `npm run build:components`, then `npm run codegen:dts` to
 * regenerate; or hand-author this file fully if rich event types are
 * needed beyond what the yaml `events:` block can express.
