ElementRef type

Element ref node - wraps created elements for tree structure Forms doubly-linked list with prev/next pointers for efficient sibling traversal Links to parent for tree traversal Tracks child NodeRefs for tree walking (needed for SSR fragment detection)

Signature:

export type ElementRef<TElement> = BaseRef & {
    status: typeof STATUS_ELEMENT;
    element: TElement;
    parent: ElementRef<TElement> | null;
    prev: LinkedNode<TElement> | null;
    next: LinkedNode<TElement> | null;
    firstChild: LinkedNode<TElement> | null;
    lastChild: LinkedNode<TElement> | null;
};
