+CodeBlock コンポーネントを追加し、Card と Anchor のスタイルを見直し
+
+- CodeBlock コンポーネントを新規追加。クリップボードコピー機能を内蔵し、シンタックスハイライト済みの React 要素を children で注入可能(shiki 等は非内包)
+- Card の視覚変更: border を `--color-primary-9` に変更し、box-shadow を削除
+- Anchor `variant="button"` の視覚変更: Button と統一(角丸を `calc(var(--size-radius) * 0.5)` に、フォーカスリングを outline 方式に、disabled 表現と transition を Button と同一に)
