feat(demo): typing splash + intro on every fresh visit; neutral desktop Cloud tabs

- Demo boots at '/' (first visit or a browser refresh) always start with
  the typing splash into the onboarding intro — the per-calendar-day
  gate is gone. In-session SPA navigation never replays it, and
  deep-route refreshes keep the visitor's place.
- Cloud top-level tabs return to the standard mode-switcher style on
  desktop; the orange full-width switcher stays mobile-only.
