   - Use TypeScript strict mode (see `tsconfig.*.json`).
   - Linting: ESLint config in `eslint.config.js`.
+  - Styling: Tailwind CSS is present. Prefer utility classes; keep minimal component-scoped CSS. Global/base styles live in `src/index.css`. Avoid inline styles and CSS-in-JS unless necessary.
 
 ### Frontend API Client (required)
 All frontend API calls must use the shared client at frontend/src/api/Client.ts.
