// Minimal eSignet stand-in for the e2e stack. freight-api-e2e's
// FAYDA_TOKEN_ENDPOINT / FAYDA_USERINFO_ENDPOINT point here instead of the
// real (unreachable) Fayda infrastructure. It does not validate the
// client_assertion, code, or code_verifier it's sent — Cypress drives the
// verification via the API directly (POST start, then POST complete with a
// throwaway code), never through the real popup+SMS flow, so nothing here
// needs to be cryptographically real, only shaped like a working OIDC token
// + userinfo response.
