Integration
The reusable source is written to @components/roadmap-1.tsx.
The registry also includes app/roadmap-1/page.tsx as a complete preview route; an existing application can keep the reusable component files without adopting that route.
Example content is isolated in @components/data/roadmap-1-data.ts (roadmapColumnOrder, roadmapColumnLabels, simpleRoadmapCopy, roadmapEntries); replace those fixtures with application data rather than editing layout markup in several places.
The roadmap intentionally models Now, Next, and Later rather than date promises; replace roadmapEntries while preserving that ordered status model.
