Из pair-view: meta-data com.rayneo.mercury.app=true — очки распознают
приложение как AR (без неё открывалось как обычное). Тема
Theme.ViewMateGlasses (чёрный фон, fullscreen), screenOrientation
landscape, hardwareAccelerated. Плюс фикс краша: prefs читались в
конструкторе Application (до attachBaseContext) — перенесено в onCreate.
Проверено на железе: открывается через лаунчер нормально.
