BlommeJan/Manim-Motion ? reverse-engineered prompt

Build me a browser based Manim editor that feels a bit like Figma for math animations.

I want a clean Vue app where I can drag shapes onto a canvas, move and resize them, edit their properties, add LaTeX equations and axes, and build animations on a simple timeline. It should support light and dark mode, undo and redo, copy and paste, and a nice desktop style menu bar. I also want a code only mode where I can just write Manim Python directly and see render errors in the UI.

Please make it able to export the generated Python and render a real MP4 through Docker, with project save and load working locally too. If needed, look up the current Manim docs online so the generated code and render flow are correct. Keep the interface polished and practical, like something a student or teacher could actually use to make math videos from the browser.
