// the proof layer
Pull a book off the shelf and its demo boots right here in your browser — real code, zero servers, nothing shared between visitors.
Every demo is scoped to your browser — no visitor ever sees another visitor's data.
Nothing here talks to a live server or database, so there is nothing to breach or exhaust.
No API keys or credentials ship to the client; live AI calls are disabled rather than proxied.
Strict content security policy, frame ancestry locked to this origin, referrers stripped.
