/**
* Every payment a 402 offers, whichever protocol states it: x402 entries from
* `PAYMENT-REQUIRED`, MPP challenges from `WWW-Authenticate: Payment`. The
* wrong-rail error lists these and names the rail switch that would pay the
* first one (spec `tenant-x402-payment-client-surface`).
*
* Parsed without the paid stack: an x402-only install has no `mppx`, and the
* error still has to say what the seller wanted.
