/**
 * Abstract base class that all custom widgets should extend.
 *
 * This class provides the interface needed for GridstackItemComponent to:
 * - Serialize/deserialize widget data
 * - Save/restore widget state
 * - Integrate with Angular lifecycle
 *
 * Extend this class when creating custom widgets for dynamic grids.
 *
 * @example
 * ```typescript
 * @Component({
 *   selector: 'my-custom-widget',
 *   template: '<div>{{data}}</div>'
 * })
 * export class MyCustomWidget extends BaseWidget {
 *   @Input() data: string = '';
 *
 *   serialize() {
 *     return { data: this.data };
 *   }
 * }
 * ```
