+/**
+ * EditorBlock Component
+ *
+ * A Monaco-based code editor component that mirrors the visual style of CodeBlock.
+ * It supports syntax highlighting, theme integration (light/dark), full-screen mode,
+ * and copy-to-clipboard functionality.
+ *
+ * Usage Example:
+ * ```tsx
+ * import EditorBlock from '@/components/theme/editor-block';
+ *
+ * function MyComponent() {
+ *   const [code, setCode] = useState('console.log("Hello World");');
+ *
+ *   return (
+ *     <EditorBlock
+ *       value={code}
+ *       onChange={setCode}
+ *       language="javascript"
+ *       height="400px"
+ *     />
+ *   );
+ * }
+ * ```
+ *
+ * Required Packages:
+ * - @monaco-editor/react
+ * - lucide-react
+ * - clsx
+ * - tailwind-merge
+ *
+ * Note: This component is client-only and will render a placeholder during SSR.
