okanfx/hairline ? reverse-engineered prompt

Build me a little interactive graphics library called hairline, with a demo site too.

It should show a set of isometric line figures that respond to the pointer in playful ways, like cards lifting, pillars rising, a phone opening, a lock moving, a turntable spinning, things like that. I want it to work in React and also in plain browser code, so the same figure can be used as a React component or attached to a DOM element. Each figure should fit its container, keep a 5 to 4 shape, and feel smooth and responsive when I move the mouse or use the keyboard where it makes sense.

Please include a simple way to control how strong the motion feels, plus light and dark styling that can follow the page theme. Make sure it is accessible, has sensible labels, and can be updated or destroyed cleanly. If you need to look up current docs online for any details, go ahead.
