 ## Dev
 
-Source code is in TypeScript in `./ts`.
+Requires **Node.js >= 24**. Source code is TypeScript in `./ts/` — tests run directly from source (Node 24 type stripping).
 
 ```bash
-npm run build          # TypeScript + webpack bundle
-npm run test           # Node tests
+npm test               # Run tests (from ts/ source, no build needed)
+npm run build          # Webpack bundle (dist/)
+npm run lint           # ESLint
 npm run test:coverage  # Coverage report
 ```
 
+`tsc` is only used by the `prepare` script for npm/git-dep consumers.
+
 Browser test suite: build then run `npx backloop.dev ./dist` and open `https://l.backloop.dev:4443/tests.html`
