-Added `EntityInfoCard` component to `@backstage/plugin-catalog-react` as a BUI-based card wrapper for entity page cards. Migrated `EntityAboutCard`, `EntityLinksCard`, `EntityLabelsCard`, `GroupProfileCard`, and `UserProfileCard` from MUI/InfoCard to use the new BUI card layout. Replaced MUI ImageList and Grid internals in LinksGridList and AboutContent with BUI Grid. Migrated EntityLabelsCard from core-components Table to BUI Table. Updated GroupProfileCard and UserProfileCard to use BUI Avatar in card titles.
+Migrated `EntityAboutCard`, `EntityLinksCard`, `EntityLabelsCard`, `GroupProfileCard`, and `UserProfileCard` from MUI/InfoCard to use the new BUI card layout and BUI components where possible.
+
+**BREAKING**: Removed `variant` prop from EntityAboutCard, EntityUserProfileCard, EntityGroupProfileCard, EntityLabelsCard, EntityLinksCard
+
+**Migration:**
+
+Simply delete the obsolete `variant` prop, e.g:
+
+```diff
+-      <EntityAboutCard variant="gridItem" />
++      <EntityAboutCard />
+```
