Make recurring meetups stick

Recurring plans fail when every meetup starts from scratch.

Make the process automatic: same rough window, clear RSVP expectation, rotating organizer.

Simple recurring structure

1. Pick one default cadence (weekly, bi-weekly, monthly)
2. Decide one fallback window if the main slot conflicts
3. Lock the next date before ending the current meetup

Consistency beats intensity. Smaller, regular meetups are easier to sustain.
