TypeSafe Jev tests

Flight notes
Paste a public URL. Jev judges the first screen: wall, promise clarity, CTA, pricing, trust and an overall verdict, as fast typed decisions with probabilities rather than an essay.
The server validates and fetches the page with DNS and redirect checks against private and metadata addresses, strips scripts and caps the text, then asks all six questions in one systemOne request. No page data, URLs or identities are stored.
