# src/ui — deprecated in favor of `ui/` Original plan for this folder was a Streamlit demo. We upgraded to a proper React + Motion + R3F frontend that lives at the repo root under `ui/`. Streamlit couldn't carry the Paper & Ink design language (custom fonts, theme variables, kinetic typography, 3D scene), so we swapped stacks. To run the UI: ```bash cd ui npm install npm run dev ``` See `ui/README.md` for the full picture.
