/**
 * Instrumented tests for [Modifier.bottomNavigationHeight].
 *
 * Each compact bottom-nav display mode maps to a specific bar height:
 *  - [BottomNavDisplayMode.ICON_ONLY]      -> 56.dp (fixed)
 *  - [BottomNavDisplayMode.TEXT_ONLY]      -> 44.dp (fixed)
 *  - [BottomNavDisplayMode.ICON_AND_TEXT]  -> min 80.dp (can grow)
 *
 * We apply the modifier to a tagged [Box] and assert the resulting height on
 * a real Compose host (this requires the instrumentation test runner, hence
 * androidTest rather than the Robolectric-free JVM test source set).
