The v-app component is REQUIRED for all applications. This is the mount point for many of Vuetify’s components.
v-app should only be rendered within your application ONCE.

Application components

Each of these application components have a designated location and priority that it affects within the layout system.

• v-app-bar: Is always placed at the top of an application with a lower priority than v-system-bar.
• v-bottom-navigation: Is always placed at the bottom of an application with a higher priority than v-footer.
• v-footer: Is always placed at the bottom of an application with a lower priority than v-bottom-navigation.
• v-navigation-drawer: Can be placed on the left or right side of an application and can be configured to sit next to or below v-app-bar.
• v-system-bar: Is always placed at the top of an application with higher priority than v-app-bar.
