 ## Testing & Monitoring
 
+### Testing Strategy
+- **End-to-End Tests**: Playwright for critical user flows and authentication
+- **Test Configuration**: `playwright.config.js` configured for localhost:3000
+- **Test Files**: Pattern `test-*.js` and `test-*.cjs` for various scenarios
+- **Test Execution**: Tests assume server is running (use `npm run dev` first)
+- **Authentication Tests**: Comprehensive login/logout flow validation
+- **Mobile Testing**: Responsive design and mobile menu testing

+## Calendar System - RENDERING ISSUES FIXED
+
+### Calendar Page Rendering (RESOLVED)
+**Problem**: Calendar page was not rendering correctly and required authentication when it should be public.
+
+**Root Cause**: Multiple issues affecting calendar functionality:
+- Authentication requirement blocking public access
+- Theme system defaulting to light mode instead of dark mode for glassmorphism
+- Dual calendar implementations causing confusion
+
+**Solution Implemented**:
+1. **Made Calendar Public**: Removed authentication requirement from `/src/pages/calendar.astro`
+2. **Fixed Theme System**: Changed default theme to dark mode for better glassmorphism appearance
+3. **Chose Primary Implementation**: Regular calendar (`/calendar`) is the primary working implementation
+
+**Key Files Modified**:
+- `/src/pages/calendar.astro` - Removed auth requirement, fixed theme default
+- `/src/pages/calendar-enhanced.astro` - Removed forced dark mode theme blocking
+
+**Current Status**: 
+- ✅ Calendar page loads correctly at `/calendar` 
+- ✅ Beautiful glassmorphism theme with purple gradients
+- ✅ Full calendar functionality (navigation, filters, search, view toggles)
+- ✅ All navigation links point to working calendar page
+- ✅ Responsive design works on desktop and mobile
+- ⚠️ Enhanced calendar at `/calendar-enhanced` has React component mounting issues (not used in production)
+
+## Development Workflow
+
+### Code Quality Standards
+- **ESLint**: Configured with TypeScript support and custom rules
+- **Astro Files**: ESLint parsing disabled for `.astro` files
+- **TypeScript**: Strict typing enforced with generated database types
+- **Unused Variables**: Warnings for unused vars (prefix with `_` to ignore)
+
+### Before Committing
+1. Run `npm run lint:fix` to fix code style issues
+2. Run `npm run typecheck` to validate TypeScript
+3. Run `npm run build` to ensure production build works
+4. Test critical flows with `npx playwright test`
+
+### Development Server
+- **Port**: Defaults to 3000 (configurable via PORT env var)
+- **HMR**: Hot module replacement enabled on all interfaces
+- **Security**: Origin checking enabled for production security
