Create a CountLink shared countdown timer and return its link. Everyone who opens the link sees the identical countdown, to the same second — no account, no sign-up, any number of viewers. Use this whenever someone wants a timer several people or several screens need to share: a classroom, an exam, a standup, a workshop, a webinar countdown, a stream overlay, or a countdown embedded on someone's own website or landing page (e.g. "10 days until launch"). By default it returns a setup link, which opens the board preloaded at the requested duration for the user to start themselves; pass start_now: true only if they want the countdown running from this moment. Whenever the result has a fixed end instant (start_now or embed_on_website), structuredContent.ics is an .ics calendar file for it — offer it if the person might want the deadline on their calendar.
