 * A button group visually organizes multiple related buttons into a single
 * collection.
 *
 * The component exposes `role="group"` via ElementInternals; authors do not need
 * to set it.
 *
 * For a toolbar pattern, wrap the group in an element with
 * `role="toolbar"`. When there is more than one toolbar, each must have an
 * accessible name (`aria-label` or `aria-labelledby`). For vertical toolbars, set
 * `aria-orientation="vertical"` on the toolbar element.
 *
 * For further accessibility details, see the [Accessibility](/elements/button-group/accessibility/) documentation.
