SignatureKit
Concepts

Mental model

The mental model behind SignatureKit: signer boundary, Effect runtime, document formats, browser A1, and remote requests.

Signer boundary

Where signing power enters the system.

Effect runtime

Why public APIs return typed Effect values.

Document formats

Why PDF and XML mutate documents, not signers.

Browser PDF flow

Where React ends and Effect signing begins.

Remote requests

How provider requests differ from local Signatures.

Browser PDF flow

Read a PDF, build the A1 signature placement template, and sign with the browser helpers.

Signer boundary

A signer owns where signing power comes from; formats own document mutation.
