// Web e2e scenario: the collapsed rail's search control in the real event
// order. The rail click flips the sidebar wide and mounts WorkspaceBrowser's
// outside-click dismissal listener during its own React dispatch; the same
// click then keeps bubbling to document with the unmounted rail button as its
// target — outside searchRoot. The package-level jsdom test cannot replay
// that continuation (fireEvent does not re-bubble through listeners mounted
// mid-dispatch), so the guard that keeps the gesture alive
// (.agents/notes/implemented/bug-fix/2026-08-18-rail-search-outside-click-self-dismissal.md)
// is pinned here, in the assembled application under a real browser click.
//
// Zero model calls: collapsing the sidebar and expanding the search are pure
// client layout gestures; the scenario needs no session content at all.
