On shutdown the full article list (including current read/unread state) and the ID of the open article are saved to ~/.local/share/net.jeena.FeedTheMonkey/cache.json. On next launch: - The cached articles are loaded into the list immediately, before any network request, so the sidebar is populated and the previously open article is visible without waiting for the server. - The article content is injected into the WebView once its base HTML finishes loading (LoadEvent::Finished), avoiding a race where window.setArticle() did not yet exist. - A background refresh then fetches fresh data from the server; if the previously open article still exists its selection is preserved, otherwise the first item is selected. - Network errors during a background refresh show a toast instead of replacing the visible article list with an error page.
