+ *
+ * e.g. These 2 types are still strings, but they are unique from each other:
+ * declare const UserID: Brand<string, 'userId'>;
+ * declare const RoleID: Brand<string, 'roleID'>;
+ *
+ * This protects against accidentally assigning one type to another.
+ * const roleId: RoleID = '123';
+ * const userId: UserID = roleId; // Compiler error
