// We need to be careful with Shadow DOM and Monaco.
// Monaco appends to the body by default for overlays, but we want it inside our component.
// Simplest way for this demo: Target by ID inside ShadowDOM
// Because Monaco is a bit complex with ShadowDOM encapsulation (styles/events),
// we might need to use global or trick it.
// For this demo, let's attach to the specific ID if possible, or use window.monacoEditor for control.
// Note: Monaco doesn't fully support ShadowDOM out of the box easily without configuration tweaks.
// We will try to render it. If it fails, it might be due to the shadow root encapsulation blocking some global styles/events needed by Monaco's widget logic.
// To make it robust, we often put the monaco container *outside* or pass specific options.
// Let's try standard initialization on the element found in the shadowRoot of the custom element.
