binzam/react-onboarder ? reverse-engineered prompt

Build me a React and Next.js onboarding tour component library that feels polished and easy to drop into an app.

I want a guided tour provider with a dimmed overlay, a highlighted target area, and a card that stays inside the viewport and points to the right spot without messing up the page layout. It should be type safe so I can define my own set of target ids and get compile time errors if I mistype one. Make it work well with Tailwind, Framer Motion, and Floating UI, and let me customize the styling or use it unstyled if I want.

It should also be friendly for Next.js App Router, include a server safe way to mark targets, and handle accessibility properly with focus management and keyboard support. Add a way to remember when a tour has already been seen, plus a way to start it automatically or manually. If you need to check current docs for any of the dependencies, go ahead and look them up online.
