SubscriptionCard shows a plan with its state, price and what comes
next, a way to change it, and Cancel after a second press or Keep plan
once canceled. UsageQuota gives each limit a meter and a line of how
much, or how far past. PaymentMethodForm tells a card's network from
its number, checks it with Luhn, and saves once the number checks out,
the month is ahead, the code is whole and a name is given; it rests
while the owner checks. BillingHistory lists bills with their state and
a download; UpgradePrompt stands as one line or as a paywall.
TeamMemberTable changes a member's role through RoleSelector and
removes after a second press, the owner staying; InvitationList
invites by a reading address with a role and resends or revokes.
