Formal billing rail.
Invoices, payment sessions, receipts, and settlement state should feel like disciplined infrastructure, not cart-driven SaaS checkout.

Billing exists here as a formal rail. Prime 88 still carries qualification. This page closes money cleanly when the route is already justified.
