- Persist a per-event "first tracked" anchor in the App Group instead of
resetting the progress start to now on every refresh (auto mode), so
the bar actually fills toward the event. Explicit "Counting from" wins
when it's before the event date.
- Make Event date / Counting from optional ("Choose") — the same-second
defaults produced a zero-length span (always 0%) and looked broken.
- Pre-render timeline entries every 30 min (12h horizon) so the bar and
time-left label move between refreshes instead of only at midnight.
