/**
 * @title EchoAccessControl
 * @author Dynabits.org
 * @notice A centralized, extensible role-based access control system for the Echo Protocol.
 * @dev Built on OpenZeppelin’s {AccessControlEnumerable}, this contract manages and registers
 *      all operational roles used across Echo modules, including Administration, Campaign Factory,
 *      RouterController, and Contents. It provides an efficient, standardized way to:
 *      - Register new roles dynamically.
 *      - Manage role-based permissions.
 *      - Enforce hierarchical role control through a Super Admin and restricted roles.
 *
 * ### Features
 * - Dynamic role registration with keccak256-based identifiers.
 * - Role restriction toggling (only Super Admin can toggle).
 * - Safe grant and revoke mechanisms using role names instead of raw bytes32 roles.
 * - Prevents unauthorized access or role revocation from Super Admin.
