Example 09 is the bounded Path widget pilot. It keeps the behavior intentionally small: one Path control publishes a path value, the diagram copies that value, and one Path indicator displays the result.

-> FIR
-> lowering
-> LLVM native path kernel artifact + manifest
-> C++ reference runtime
-> .wfrog front panel binding
-> Default Path realization SVG
The visible front panel must consume ui/path_panel.wfrog, which points to
Libraries/Realizations/Default/path.default.wfrog and the Default Path SVG
template. A fallback HTML-only Path widget is not a valid implementation of this example.
