That's a nice demo, but the text are so obviously written by Claude that I barely forced myself to read it through the end. “The client is the load-bearing part” – real people don't write like that. Asking a human editor to remove LLM slop from the text would've improved the page a lot.

Speaking about the content, I would've appreciated more details, especially for the Mallory scenario. It all looks a little bit like handwaving now: “Suppose a signature happens anyway”, how exactly could that happen and what's needed for that? ”The server throws it away”, but why exactly?
