Estiva's design tokens (the contract) and a small set of primitives (a convenience) for every Estiva app.

The Estiva wire format: Buzz-shaped Nostr event builders, NIP-01 ids, NIP-19 naddr, NIP-98 HTTP auth, and the relay clients. Speaks the protocol; interprets nothing.

Throwaway package proving the Estiva publish pipeline end to end. Not a library — do not depend on it.

Estiva ID sign-in: authorization code + PKCE, token storage, silent renewal, sign-out, signing via POST /sign, and the auth-shell state machine. Knows nothing about any app's data layer.

Render and act on another app's objects from its published NIP-89 manifest. The owner defines the projection; the consumer decides how it looks.

Browser lifecycle two Estiva apps share: the one live relay socket a tab should hold, its credential read per connect, and the network coming back.
