Membership history

Growth

2 measurements spanning 77 days, net +51. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 40–107 and does not start at zero.
