wpgraft does not care that a language model wrote the HTML, or what framework it used. It reads the page as your browser rendered it: the real elements and the real computed styles on each one, at every width you ask for. It then builds that as Figma layers: frames, text, vectors and image fills, with auto layout wherever the page was genuinely laid out in rows and columns. Nothing that arrives depends on Claude still being there.
Claude will write a whole landing page in one go, and what comes out is code. When the next step is a design review, wpgraft turns the rendered page into Figma layers: frames, text and images a designer can change and comment on without touching the HTML.
