Declared, not programmed
An app describes its configuration; the host draws the panel and validates the values, on the client and on the server, from the same descriptors.
Prezzando for developers
An app teaches the quoting assistant a trade it doesn't know — and never ships a line of code to a customer's browser.
Dictated, not suggested
A tool can attach the exact quote line that follows from its result. The model copies a reference instead of doing arithmetic, and it can’t get the numbers wrong.
Nothing implicit
Network hosts, credentials, chat abilities: what isn’t declared in the manifest isn’t reachable. The host enforces it, the manifest documents it.
Seen before shipping
npx prezzando-preview my-app.ts opens the storefront card, the settings
panel and the resulting prompt, and reloads as you save.
