Show HN: Preview and edit Material Kit React (MUI) without a build step

material-kit-react is a Vite + TS admin template. Normally you clone it, npm install, npm run dev just to look at the dashboard. I opened the folder in CrossUI Studio instead, let it generate a project setting, rendered src/main.tsx directly — no install, no build — then drilled down into the dashboard and changed a widget. Notes from actually doing it.
