        // degraded fling. Raised deliberately rather than guarded at
        // runtime: nothing this app is built for runs below 29, and an

        // on Iris's phone, and this one targeted 34 and does not
        // (2026-09-07). The emulator here is API 36 and the push-up works
        // there at either target, so the target is the only difference the
        // two devices do not share.
        //
        // The mechanism, stated as the reading it is: below targetSdk 35
        // a window keeps the legacy behaviour, where `adjustResize` shrinks
        // the window for the IME and `getInsets(ime()).bottom` therefore
        // measures the overlap with an already-shrunk window -- zero, with
        // nothing left to push up. `MainActivity`'s
        // `setDecorFitsSystemWindows(false)` opts out of that, and on API
        // 36 it still takes; Android 16 deprecated it and Android 17 is
        // where it appears not to. At 35+ edge-to-edge is not opt-in, so
        // the app is handed the real overlap without relying on a
        // deprecated call. If the phone still reports `ime_bottom=0` with
        // a nonzero `dispatches` in the Diagnostics pane, this reading was
        // wrong and the `WindowInsetsAnimation.Callback` in
        // `MainActivity` is the other half to look at.

    // untrusted VM). `build-apk.sh` generates this key once and points at it through the
