// RUM token API helper
// --------------------------------------------------------------------------
// Thin wrappers over the RUM token REST API used by the RUM E2E specs.
//   GET  /api/{org}/rumtoken  -> read current token
//   POST /api/{org}/rumtoken  -> create / reset token
// Auth works regardless of the browser storageState. Credential selection,
// org-id validation and the plain-HTTP guard live in rum-env.js — prefer a
// dedicated least-privilege account via ZO_RUM_TEST_EMAIL/PASSWORD.
