Subject: [PATCH] ui(gui): say 'window' instead of 'browser tab' in shutdown
 copy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update the Close page intro, the shutdown overlay, and the toast so
they all read "you can close this window" — clearer for users running
the app in a dedicated browser window rather than a tab.
