Localized Theme Designer

This headless-safe application imports one Dutch catalog from each framework package, adds its application catalog last, and injects the shared service into createApplication.

The action row measures the complete translated Button group before placement, so the widest Dutch caption determines equal sibling widths instead of relying on English-sized rectangles. For the broader locale and viewport sweep, run yarn workspace @jsvision/examples demo:i18n; the harness reconstructs a fresh I18n service and Application for each typed story selection.

One Dutch translation service shared by the application and every framework package.
