Class HonuaWidgetHost

Whether a usable container was resolved (requires a DOM).

The mounted element, when mount has completed.

Removes the mounted element from the container.

Ensures the injected web-component kit is registered and the element is mounted into the container. Returns the element, or undefined when no DOM / container / kit is available (headless shims, or an application that never called registerHonuaWidgetKit).

Mounts (when needed) and applies assign to the element. Fire-and-forget friendly: shims call void host.update(...) from synchronous refresh paths.
