DemoSpline is the reference application for the repository. It lives under
samples/DemoSpline, depends on Spline from src/Spline, and
provides an interactive UI for editing, loading, saving, tuning, and
visualizing spline data.
Spline.dotnet build Spline.slnx.DemoSpline to validate the runtime behavior interactively.Spline once the reusable surface is ready to publish.Keeping DemoSpline outside the package surface avoids shipping desktop UI
dependencies to library consumers while preserving a fast feedback loop for
curve behavior changes.
