2. Upgrade Vite and Vitest
3. Use @tanstack/config for packages configuration
4. Remove redundantjest.config.js files
5. Update examples to use workspace:* protocol instead of explicit version

Lit Integration

Integration for Lit by creating a Reactive Controller to create a ranger + basic example.
