//! Endpoint admission for `#[access(Protected)]` operations: the caller's IAM
//! session JWT (`Authorization: Bearer`) is verified against the JWKS at
//! `JWKS_PUBLIC_KEY_URL`, honouring `JWT_ISSUER` and `JWT_AUDIENCE`.
//!
//! Bind a protected operation with `Operation::bind_authorized(UserPolicy, handler)`;
//! the handler receives the verified `AuthenticatedSession` (subject, roles,
//! permissions and claims such as `tenant_id`) to authorize per resource.
//! `#[access(Internal)]` (HMAC) operations need a policy implementing
//! `OriginalBodySignedPolicy` instead; see that trait's documentation.
