/*:*
 * ggaze — window smoke test (integration)
 *
 * Constructs a GgazeWindow offscreen and asserts the two-view stack exists
 * (children "grid" and "large", default visible = "grid"), and that
 * ggaze_window_open titles the window with the file's basename.
 *
 * The window is built with g_object_new() (no "application" property): the
 * stack/header are constructed in ggaze_window_init, independent of the app
 * association. Setting GtkWindow:application requires the GApplication
 * ::startup signal to have fired (it does in production via activate/open;
 * not in this isolated smoke test). Needs a display, so this lives in the
 * `integration` suite (CI runs it under xvfb); skipped cleanly when no
 * display is available.
