+- **Android 15+ edge-to-edge safe-area (WebView-version-dependent, bit me on API 37).** targetSdk 36 forces
+  edge-to-edge — the WebView draws behind the status bar (top) and the gesture-nav home indicator (bottom).
+  On Android **WebView < 140**, `env(safe-area-inset-*)` wrongly reports **0**, so chrome relying on it draws
+  under the bars and is untappable: the top nav under the clock, and the game's bottom action bar's **centre**
+  button (Hint) under the home-indicator pill (side buttons still work; `navigation_mode`=2 is gesture nav).

+  default — no dep, no config) injects correct `--safe-area-inset-*`; consume them as
+  `--tg-safe-*: var(--safe-area-inset-*, env(safe-area-inset-*, 0px))` (`ui/src/app.css`). **Reproduces ONLY on
+  WebView < 140** — an emulator whose WebView auto-updated (Play Store) to ≥140 (e.g. Chrome 149) will NOT
