 - Whenever a reusable pattern appears, prefer Tailwind component patterns (`@layer components` with `@apply`) over handwritten legacy CSS; keep one-off layout details as utility classes where practical.
 - Use Playwright to inspect the rendered result after every visual change at desktop and narrow viewport sizes.
 
+## TypeScript workflow
+
+- All application, service, SQL, workflow, script and test source files must use TypeScript (`.ts`).
+- Run the project through `tsx` during development and compile the browser entrypoint from `public/app.ts` to `public/app.js` before serving it.
+- Do not add new JavaScript source files. Generated browser JavaScript is build output only.
+- Keep database safety rules and existing runtime behavior unchanged during the migration; add types incrementally to migrated modules.
+
+## Browser scraping workflow
+
+- Use Playwright for all supplier/manufacturer website scraping and browser page inspection.
+- Do not implement new scraping with raw `fetch`, regex-only HTML parsing, Selenium or direct HTTP shortcuts.
+- Scrapers must use controlled browser navigation, selectors, explicit waits and bounded request counts.
+- Keep scraping slow and observable, preserve source URL/status information, and handle blocked pages or missing selectors as explicit errors.
+- Supplier data remains a local draft until the user explicitly confirms an Apply / Save action.
+
 ## Runtime
 
 - Start the web app with `npm run dev`.
 - Open `http://127.0.0.1:3404/`.
-- The current server is `src/server.js`.
+- The current server is `src/server.ts`, run through `tsx`.
 - Configuration is loaded from `config/local.json`, merged over `config/local.example.json`.
 - `.env` exists for local MariaDB notes, but the application does not yet load `.env` automatically. Do not assume `.env` is active until configuration loading is explicitly wired to it.
