//! Account-level capabilities (entitlements) shared across services.
//!
//! Distinct from API-key [`crate::permissions`] (per key) and roles (operational). A user is
//! granted a default set at registration; the platform admin can restrict/grant per user. The
//! effective set is computed in the identity service and propagated to every service as the
//! signed `x-auth-capabilities` header; enforcement is per-endpoint via
//! [`crate::UserContext::require_capability`].
