 * A convenience wrapper combining QtQuick Controls ItemDelegate and IconTitleSubtitle
 *
 * This is an intentionally minimal wrapper that replaces the ItemDelegate's
 * contentItem with an IconTitleSubtitle and adds a subtitle property.
 *
 * If you wish to customize the layout further, create your own `ItemDelegate`
 * subclass with the `contentItem:` property set to the content of your choice.
 * This can include `IconTitleSubtitle` inside a Layout, for example.
 *
 * \note If you don't need a subtitle, use `ItemDelegate` directly.
