// Persona scenarios — auth-provider exception.
//
// web-app-keycloak IS the OIDC / OAuth2 / LDAP-federation auth provider
// itself. The generic persona-flow runners assume a downstream app
// behind a Keycloak chain; for keycloak that journey is circular (the
// "app" behind keycloak IS keycloak). The persona-equivalent coverage
// for this role lives in the bespoke role-specific tests above:
//
//   - "keycloak enforces Content-Security-Policy and exposes canonical
//     domain from applications lookup"
//                              → guest persona equivalent.
//   - "master-realm super administrator logs into Keycloak admin
//     console and logs out"   → administrator persona equivalent.
//   - "normal-realm administrator logs in through account interface
//     and logs out"            → administrator persona via account UI.
//   - "normal-realm biber logs in through account interface and logs
//     out"                     → biber persona via account UI.
//
// No generic persona scenarios are emitted; the auth-provider role is
// part of the auth-less / circular-dependency persona-collapse
// exception.

// Persona scenarios.
// Bodies live in the shared persona helpers under
// roles/test-e2e-playwright/files/personas/{guest,biber,admin}.js.
