/*:*
* ggaze — main window
*
* Implements GgazeWindow. Builds an AdwHeaderBar + a GtkStack with two named
* children: "grid" (placeholder until M7) and "large" (the GgazeViewer from
* M1). ggaze_window_open() loads the file via the loader and shows it in the
* viewer. Real file-vs-folder resolution lands in M2 (navigator); M1 just loads
* the one file. See docs/architecture.md "Responsibilities / window".
