# Custom Type Registration

> Extend the stylable element vocabulary beyond the native HTML tag set by registering each semantic type against a base tag and a `data-el` stamp; the registered type becomes a first-class node the globals layer binds one appearance contract to, so a concept no native tag can express — a field-label, an icon, a toast, an entry — is styled by its type, never by a class.
