 ## 🧪 Testing Framework
 
-This project includes a comprehensive testing framework with multiple layers of testing:
+This project uses a simplified, component‑first testing model:
+
+- **Component tests (Vitest + RTL)** live in `tests/components/` with a single file per component.
+- **E2E tests (Playwright)** cover critical user journeys and visual regression.
 
 ### Quick Test Commands
 
 ```bash
-# Unit tests with coverage
+# All component tests with coverage
 npm test
 
-# E2E tests
-npm run e2e
+# Component tests only (new structure)
+npm run test:component
 
-# Performance tests
-npm run lhci

-# Storybook tests
-npm run test:sb
