//
// Suite name "misc_widgets_ext" is intentionally distinct from every other
// suite in the test binary so case names never collide. Static helpers use
// the unique prefix "mw_".
//
// Safety rules baked in (verified against prior crashes / link failures):
//   * Only Google Test (TEST(misc_widgets_ext, ...)); no main() defined here.
//     gtest_main / the shared test main supplies entry point.
//   * Every widget is constructed fresh with a brand-new local QWidget parent
//     (stack or owned by the test) so cases do not mutate shared app state.
//   * Geometry / paint / show paths are guarded by
//     QGuiApplication::primaryScreen(); cases GTEST_SKIP() when headless so
//     they never crash in CI without a display.
//   * No mpv backend / decode / real media file / network fetch is exercised.
//     For BurstScreenshotsDialog we feed synthetic QImages; for UrlDialog we
//     drive textChanged + url() validation purely through the public API.
//   * The compositing_manager is a singleton accessed via get(); only pure
//     getter / state-toggle / safe-parser paths are exercised. Mutators that
//     flip static state are restored to their prior value at the end of each
//     case so cases stay order-independent.
