Project Nayuki QR Code generator

Rapid Cactus uses a locally bundled, pinned TypeScript/JavaScript implementation of the Project Nayuki QR Code generator, version v1.8.0 (commit 720f62bddb7226106071d4728c292cb1df519ceb). It is used only to generate pairing QR codes locally; no third-party QR service is used.

The vendored integration removes TypeScript syntax and adds named ES module exports. Project Nayuki does not endorse Rapid Cactus.

jsQR

Rapid Cactus bundles the unmodified jsQR decoder, version 1.4.0, from the cozmo/jsQR project. It decodes pairing QR codes locally from a camera frame; it has no network, telemetry, or runtime dependency.
