The screen that authors a Theme; an application opts in. Also a program: the jar names ThemeEditorApp as its Main-Class and the POM brings a backend and every fallback face, so `jbang io.github.limn-toolkit:limn-theme-editor:<version>` opens it.

The kitchen sink: every widget, the charts, the media player and the 3D viewport in one window. An application, not a library — nothing should depend on it.
