 - Use `npm run test:integration` only when backend/API behavior is touched and
   PM2/MariaDB are available.
 - `npm run build` runs unit tests before `react-scripts build`.
+- After any change that affects the production site or a PM2-served workflow,
+  also verify the live site at `https://dwroller.alw.dk` in a browser after
+  `npm run build:fast` or the equivalent deployment step. Treat local tests and
+  builds as incomplete until the live flow has been checked.
 - If tests fail because MariaDB, PM2, Ollama, or local services are unavailable,
   report that explicitly rather than masking the failure.
