Integration
The reusable source is written to @components/changelog-4.tsx.
The registry also includes app/changelog-4/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/changelog-4-data.ts (ChangeEntry, SimpleRelease, simpleChangelogCopy, simpleReleases); replace those fixtures with application data rather than editing layout markup in several places.
Release entries use ISO dates and render them through <time dateTime>. Added, improved, and fixed remain textual labels rather than color-only states.
