 Steps:
 1. In `frontend/src/pages/CreatorDetail.tsx`, find the stats span showing `{creator.view_count.toLocaleString()} views` (around line 110)

+
+**Replaced meaningless '0 views' display with topic-category counts derived from techniques array on creator detail page**
+
+## What Happened
+
+Removed the view_count reference from CreatorDetail.tsx and replaced it with a computed topic-category breakdown. The implementation reduces the techniques array into a Record of category counts, sorts by count descending, and renders inline with dot separators matching the existing UI pattern. When no techniques are loaded, the category section is hidden. No CSS changes needed.
+
+## Verification
+
+TypeScript compilation passes, production build succeeds, grep confirms topic_category usage and view_count removal. Browser verification on ub01:8096 shows topic categories rendering correctly on creator detail page.
+
+## Verification Evidence

+## Known Issues

+Data has case-inconsistent topic categories ('Sound design' vs 'Sound Design') appearing as separate entries — upstream data quality issue.
