Frame

Frame, dressed in the paper-and-ink system: a sandboxed iframe whose body renders the default slot and whose `head` slot teleports style and link elements into the frame's document — styles the child renders must travel through it. (The React wrapper takes the same content as a `head` prop; the two frameworks disagree, as Ark renders it.) The frame measures its content and grows to fit; the vessel's border and paper belong to the consumer, since an iframe carries no anatomy attributes for the core stylesheet to hook.
