+- **ALWAYS format code after making changes**: Run `pnpm run format` before committing

+- **This is mandatory for every commit** - formatting checks will fail in CI if not done
+- The workflow is:
+  1. Make your code changes
+  2. Run `pnpm run format` to format all files
+  3. Run `pnpm run check` to verify all checks pass
+  4. Fix any failing checks and repeat step 3 until all pass
+  5. Commit your changes
