A "New members" card sits beside Renewal, and the signups chart becomes a stacked
bar: bar height stays "signups this month" while the split shows where they came
from.
New means "first-ever season at this club", not "signed up recently". A member who
lapsed for a year and came back is a renewal, and counting them as new would
flatter every recovery into growth. It is also per club, not per platform: someone
who plays for another club is still new here.
The split resolves each member's earliest season once up front rather than asking
per row, so the chart costs two queries instead of one per membership.
