No account, no login. Each proposal carries its own token and is never publicly listed.

A signature, and a record
that can’t quietly change.

The signed version stays signed. Later edits to the live proposal never reach it, and every signature carries its own independent audit row.

The exact document, frozen
Structure, pricing, selected options and brand tokens are captured as signed, then never overwritten.

Edits
The live copy stays editable
Changes after acceptance apply going forward. The version they signed is untouched.
The document is frozen at acceptance: structure, pricing, selected options and brand tokens, exactly as it read on screen.
Signed-at time, hashed IP, device and the signer's verified email are set by the server, not the browser.
Change the live copy afterwards and the signed version is untouched. Both stay available side by side.
