Build high-performance VueJS user interfaces (SPA, PWA, SSR, Mobile and Desktop) in record time

// We cannot reference directly Capacitor/Cordova types
//  or they would generate TS errors for Vue CLI users
// We also cannot move feature-flags system into `@quasar/app-webpack`/`@quasar/app-vite`
//  because `QVueGlobals` augmentations won't be transferred to
//  the `vue/types/vue` augmentation for unknown reason (probably TS limitations)
//  and the system will just stop working
// To workaround these problems we define an empty holder interface
//  and augment it into `@quasar/app-webpack`/`@quasar/app-vite` with current typings
