 * NuralyUI Code Editor component using CodeJar — a lightweight (~2KB) code editor.

 * @example
 * ```html
 * <nr-code-editor
 *   language="javascript"
 *   theme="vs-dark"
 *   .code=${"console.log('Hello');"}
 *   @nr-change=${(e) => console.log(e.detail.value)}
 * ></nr-code-editor>
 * ```
 *
 * @fires nr-change - Fired when the code content changes
 * @fires nr-keydown - Fired on keydown events in the editor
 * @fires nr-keyup - Fired on keyup events in the editor
 * @fires nr-focus - Fired when the editor gains focus
 * @fires nr-blur - Fired when the editor loses focus
 * @fires nr-ready - Fired when the editor is ready
 *
 * @csspart editor-container - The container wrapping the editor
