* `@usefy/qr-scanner/headless` — the framework-free surface.
*
* Zero React in this graph and, deliberately, **no `"use client"` banner**
* (SPEC decision #1): a server component, a Web Worker, or a plain script can
* import from here and decode a QR code with no client framework at all.
* `src/headless.test.ts` asserts the built bundle keeps that promise.
