// Payment provider registry.
//
// Every provider is either:
//   - 'automatic': the gateway itself confirms the payment (webhook/invoice
//     settlement) and the booking is auto-approved on success. No admin involved.
//     Currently Lightning; future online gateways (e.g. Stripe) go here.
//   - 'manual': a human must verify the money arrived (TPago, bank transfer,
//     card handled offline, cash at the door). These are never auto-confirmed
//     and never auto-failed; an admin settles them by hand. Bank transfer and
//     TPago additionally expose an online "I've paid" step that moves the
//     payment to 'pending_approval'.
//
// Capacity note (see lib/capacity.ts): only paid/checked-in tickets and
// 'pending_approval' payments hold a seat. A bare 'pending' payment — of either
// kind — holds no seat, so an abandoned checkout can never block sales.
