# Deprecated — do not use
This static HTML prototype is **dead**. It posts to `/api/calculate`, which no longer exists.
Use the supported workbench instead:
- Frontend: [`apps/web`](../apps/web) (Next.js, http://localhost:3000)
- API: `cargo run -p entropyk-demo --bin ui-server` (http://localhost:3030)
- CLI: `cargo run -p entropyk-cli -- run config.json`
This folder may be removed in a future cleanup.
