Four Ramp tabs wired to the live admin/ramp/* APIs (orders reverse/complete with 409 code branching, spread CRUD, revenue window, treasury reserves/ netting/rebalance). Tables follow the Users & KYC pattern (DataTableCard + zustand filter stores + shared PaginationBar); stuck orders keep inline leg expansion.
