OpenElement relies on web-platform contracts rather than a proprietary registry product. Custom Elements, DSD, CEM, Request/Response and FormData define the direction of the public application model.
Standard Custom Elements and Declarative Shadow DOM define the durable component boundary.
Request, Response and FormData are the basis of the 0.42 loader/action surfaces — application interaction without a proprietary transport.
Element, App, Adapter Vite, Create and optional UI are the current consumer surface; internal contracts stay internal.
