Totality Editor

Live-editable editor for hacking on simulations and quick tools.
In-browser editor (kinda like CodeSandbox) for simulations.
End goal: want to get editor similar to The Book of Shaders https://thebookofshaders.com/, where I have full control of the editor.
Kinda like http://observablehq.com's Observable Notebook (Which is JavaScript cell) -- but wants to be developer-oriented.
Want to be fast and live-editable like Chakra's documentation. Want live code reload experience like Quokka, Wallaby, DataSpell.
Should be dev-friendly like Glitch.
Copy Ideas from ObservableHQ, JetBrains DataSpell, Jupyter.
Can Support multiple renderers: React, JavaScript, Python, etc.
Wants to be embeddable in my blog, like MDX components.
Monaco Editor with configurable Vim keybinding.
Want "Open as Full Playground" so they can edit the code in fullscreen editor.
"Open Project Locally" so they can fork & try locally in VSCode.
