+/*:*
+ * 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.
