UnoCSS Inspector — Next.js

Next.js app using UnoCSS through @unocss/postcss, hosting the inspector with @devframes/next — no Vite involved.

The catch-all route at app/%5F_unocss/[[...path]]/route.ts builds a standalone UnoCSS context (scanning app/** once at startup via createStandaloneInspectorDevframe) and serves the inspector SPA + RPC side-car through createDevframeNextHandler.

pnpm install
pnpm dev

Open http://localhost:3000/__unocss/ and enter the one-time code printed in the Next dev terminal to unlock the inspector.

Note: the standalone context scans the project once at startup — restart the dev server (or re-save the route file) to re-scan after adding new utilities.
