// Web e2e scenarios: lifecycle & chrome — the workspace-aware first-send
// flow over the real wire, reload recovery, and the dark-mode token cascade.
// One tiny recorded turn (text-only) drives the whole spec: the empty-state
// hero materializes a real Workspace + Session on first send (the jsdom
// workspace-flow suite pins the object-layer state machine over the fixture
// client; THIS spec pins the same flow through HTTP RPC + WebSocket + the host
// gateway), reload replays everything from the log (zero further model
// calls), and the theme scenario proves the shipped dark palette actually
// cascades: attribute -> alias token flip -> painted surface change. No
// theme/layout golden: aria snapshots are color-blind (lane scope: the
// browser-e2e-lane Agent Note); the hero's waiting state gets the one golden
// here.
