Growth

36 measurements spanning 23 days, net +114,603. 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 33,462–182,445 and does not start at zero.
