Dark theme & gesture navigation
summary
Android Q adds a system-wide Force Dark that claims up to 60% foreground power savings, applies at render time (opt‑in via theme attribute android:forceDarkAllowed) and works with WebView and Custom Tabs; AppCompat DayNight (AppCompat 1.1+) backports night theming to API 14 and adds AUTO_BATTERY (API 21+) and activity recreation on mode change; Material Components 1.1 supplies elevation overlays and MaterialShapeDrawable helpers; gesture nav standardizes back/home/overview, adds window insets and system‑gesture insets, and exposes setSystemGestureExclusionRects to opt small edge rects out of back handling.
