 **Potential Causes:**
+
 1. Svelte version mismatch (kit vs core)
 2. Missing peer dependencies
 3. Breaking changes in Svelte 5
 4. Build configuration issues
 
 **Recommended Next Steps:**
+
 1. Update Svelte/SvelteKit to compatible versions
 2. Check peer dependency warnings
 3. Review Svelte 5 migration guide
 4. Test with different Svelte versions
 
 **Workaround Until Fixed:**

 - Use smoke tests for basic validation
 - Manual testing in browser
 - Backend API testing (now fully functional)

 ## 🔍 Lessons Learned
 
 ### Backend
+
 1. **Standalone is better:** Self-contained services easier to debug
 2. **Mock early:** Mock implementations speed up development
 3. **WebSocket testing:** Real-time features need proper testing infrastructure
 
 ### E2E Tests
+
 1. **Preview > Dev:** Production builds more stable for testing
 2. **Timeouts matter:** Generous timeouts prevent false negatives
 3. **Load strategies:** Match strategy to what you're testing
 4. **Smoke tests:** Basic tests catch fundamental issues early
 
 ### General
+
 1. **Incremental fixes:** Fix one issue fully before moving to next
 2. **Test as you go:** Verify each change immediately
 3. **Document decisions:** Future you will thank present you
