 | Concern | `CanonWindow` | Why |
 |---|---|---|
 | Frameless chrome integration | Always frameless; ignores `FramelessWindow` and is not tracked by `trackPersistentDialog()` | The style guide's rounded, title-bar-less window *is* the design; native chrome would put a title bar over it |
-| Geometry persistence | None by default: asks to open centred on its parent every time (Wayland compositors place top-level windows themselves and may ignore it). `setGeometryKey()` opts in: size and position are saved under that AppSettings key on move and resize (in memory) and whenever the window hides (flushed — Escape and ⌘W / Ctrl+W hide it without a close event), and restored in place of the centring.
