// ShellPage — page object for the authenticated app shell (sidebar + content)
// and the Home page it lands on. Locators are semantic: the sidebar exposes a
// named navigation landmark, a complementary landmark, and accessible-named
// buttons (Sign out, Toggle sidebar). The redesign added `aria-expanded` to the
// collapse toggle and an `aria-label`ed connection status so the collapse and
// connection state are assertable without CSS classes.
