/**
 * @summary Sidebar group represents a navigable parent item within the sidebar that can have nested children.
 * Groups support multiple levels of nesting and show nested items in a drawer overlay or submenu.
 * Groups can be used to organize related sidebar items into expanding/collapsing sections.
 *
 * Behavior varies by nesting level:
 * - Level 1 (root): Clicking opens drawer overlay showing all nested children. Keyboard: ArrowRight opens drawer.
 * - Level 2+ (nested): Clicking toggles submenu visibility. Keyboard: ArrowRight toggles submenu.
 *
 * @slot default - Insert sgds-sidebar-group or sgds-sidebar-item elements as nested children
 * @slot indicator - Display after the label text. A chevron is auto-appended. Typically used to show badges or other indicators for the group.
