 *
 * @see {@link https://css.squidit.com.br/components/toast}
 *
 * @deprecated Use SqToastService instead for better testability and Angular integration.
 * SqToastService provides Observable-based lifecycle, data-test attributes, and proper mocking support.

 * @example
 * // OLD (deprecated):
 * this.toastHelper.toast.success('Message');
 *
 * // NEW (recommended):
 * this.toastService.success('Message');
