Ark is a headless UI component library that delivers accessible, cross-framework primitives with behavior governed by finite state machines. It provides unstyled components that encapsulate logic and accessibility — including full keyboard navigation, focus management, and WAI-ARIA support — while leaving visual styling entirely to the consumer. Components expose scoped data attributes for CSS targeting and use state machines to produce predictable, testable interactive behavior across every state transition. The library distinguishes itself through a state propagation model that distributes

jquery-qrcode is a client‑side QR code generator built as a jQuery plugin. It creates QR code images entirely in the browser without sending data to an external service, making it suitable for offline usage and reducing network dependencies.
