targetSdk 36 forces edge-to-edge, so the WebView draws behind the system
bars. On Android WebView < 140, env(safe-area-inset-*) wrongly reports 0, so
the app chrome (which only read env()) drew under the status bar (top nav
untappable) and the gesture-nav home indicator (the game's centre Hint button
intercepted; side buttons fine). Capacitor 8's SystemBars core plugin (built
into @capacitor/core, insetsHandling:'css' by default) injects the correct
--safe-area-inset-* values on every WebView; consume them ahead of env():
--tg-safe-*: var(--safe-area-inset-*, env(safe-area-inset-*, 0px))
Web / PWA / Telegram / VK are unchanged (--safe-area-inset-* is unset there,
so it falls back to env()). Verified on-device (Pixel_10 / API 37) via the
injected var — the emulator's auto-updated WebView 149 hides the env() bug,
so the visual alone won't reproduce it.
