     *   <div>{{ model }}</div>
     * </template>

     *
     *
     * // file: MainComponent.vue
     * <template>
     * <!-- preserve reference of model -->
     *   <MyComponent v-model="model" />
     *
     * //   <!-- or -->
     *   <MyComponent :model-value="model" @update:model-value="(obj) => model = obj" />
