Builds property editor UIs for Umbraco's backoffice using the modern TypeScript/Lit element approach. Pulls from official docs and includes working examples with UmbElementMixin, proper event dispatching, and configuration setup. The built-in schema alias table is genuinely helpful since mismatching client UI to server schema causes 404 errors that aren't obvious. Covers the full workflow from manifest to element implementation, though you'll still need the C# side if you want custom data validation. Good troubleshooting section addresses the common gotchas with JSON persistence and UUI components.
